Massachusetts College received various inquiries and scheduled interviews, but fortunately, Dr. Keynes was prepared, and he announced that Ye Hao, the discoverer of the new material, was conducting relevant experiments in the laboratory and had obtained more data, so he could not be interviewed now. As for the specifics of the new material, the discoverer himself will present an update on the progress of the experiment at the graduation ceremony of the Massachusetts Institute.

Ye Hao did not stay at MIT as Dr. Chen said, and after revising and refining his thesis (which was actually ghostwritten by Andy), he left MIT and returned to Jinshan City.

Since sending the details of the stealth paint back to Huaxia, Jiao Jiangbo has been very worried, a Huaxia is happy to get this top-secret information, and he is afraid that he will wake up one day and hear the news that the American government is crazy. If it weren't for the training of years as a diplomat, he would have been unable to maintain a calm expression, but even with the lightness of his face, he has inevitably made several mistakes in his work in recent days. Although the problem is not big, and was found and corrected in time. Fortunately, the consul general should have understood that Jiao Jiangbo had a special mission and secretly had some speculations, so he did not blame, but only hinted that other colleagues in the consulate temporarily helped Jiao Jiangbo share some work.

A few days later, Jiao Jiangbo slowly adjusted his mentality, whether it was a blessing or a curse, and he couldn't avoid it, so he quickly adjusted his work status and joined the daily work of the consulate.

Who knew that the sky did not obey people's wishes, just a few days after his birthday, Jiao Jiangbo's peaceful life was broken again.

One day in early June, when Jiao Jiangbo was doing official business in his office, the mobile phone in the inner pocket of his suit rang again.

"The end of the vast world is my ...... love", he was slightly stunned, Jiao Jiangbo quickly took out his mobile phone: "Hello!"

"Hello, Mr. Military Attaché, I wonder if I have the honor to invite you to meet me?"

Jiao Jiangbo thought to himself: It's finally here. The other party asked him to meet to have a showdown, after all, there is always a purpose for giving two gifts in a row. China has long expected this, and there is no free lunch in the world. Hua Xia was also very satisfied with these two gifts, and at the same time very curious about the purpose of the other party.

The other party was able to know his identity, and Jiao Jiangbo was not surprised, the other party had the ability to obtain two top-secret materials, and it was a piece of cake to investigate a consulate military attache with a semi-public identity.

"I'd love to. I am waiting for your invitation at any time!" Jiao Jiangbo hinted in his words: I have been waiting for you for a long time.

"At five o'clock this afternoon, the Nanjiang family in Chinatown, you said that you had an appointment with Mr. Wu. ”

…………………………………………………………

Chinatown is located in the city of Jinshan

At five o'clock in the evening, Jiao Jiangbo came to Chinatown as agreed after putting on makeup. After entering the Nanjiang house, I was led by the waiter to the No. 205 box, and there was already a man waiting in the box.

Jiao Jiangbo sat down and took a closer look, the other party was an Asian, wearing a white casual suit against the backdrop of a straight figure, his height was about 1.7 meters, and he had a pair of sunglasses on his face, so he couldn't see his face clearly.

The waiter waited for Jiao Jiangbo to sit down and said, "Two gentlemen, are you going to serve the food now?"

The man nodded and said, "Just follow the previous order." ”

"Okay, please wait. The waiter left the box after speaking.

The man took off his sunglasses and smiled and said, "Hello Mr. Jiao, you can call me Robert." ”

"Hello Mr. Robert, it's a pleasure to meet you!" Jiao Jiangbo found that the man had a public face, which belonged to the type that could no longer be found if he was lost in the crowd. However, the occasional flash of light in his eyes showed that he was different.

While waiting for the food to be served, the two began to chat, and after a while, they became as warm as two old friends who hadn't seen each other for many years.

Nanjiang people are high-end restaurants in Chinatown, and the food is served quickly. After waiting for the dishes to be served, the two stopped talking and silently ate by themselves.

However, Jiao Jiangbo's mind was obviously not on eating and drinking, and he put down his chopsticks after eating for more than ten minutes.

Ye Hao didn't care about Jiao Jiangbo's thoughts, he hadn't eaten well since he came back from the end of the world, and this meal was still a Chinese food, so he comfortably packed a large table of food into his stomach.

Jiao Jiangbo looked at Ye Hao, who was eating a large piece, and was surprised by his amazing appetite, such a table of meals was enough for four or five people to eat, but he didn't move a few chopsticks, and a table of meals was handled by Ye Hao alone.

Half an hour later, Ye Hao looked up and saw the shocked look on Jiao Jiangbo's face, and sneered: "I'm sorry, Mr. Jiao, I haven't had a normal meal for several days, so I make you laugh!"

"It's okay, it's a blessing to be able to eat. Jiao Jiangbo said politely.

Wiping his mouth with a tissue, Ye Hao spoke: "Mr. Jiao, you must have understood my intentions. ”

"Hmm," Jiao Jiangbo replied vaguely.

Ye Hao didn't care, although he had cooperated twice, but after all, it was the first time they met, and it was normal for Jiao Jiangbo to have suspicions. Immediately take out a safe from under the table.

Jiao Jiangbo's eyes lit up when he saw the safe, this safe was exactly the same style as the previous two, and it seemed that it should be his trading partner. However, he still maintained the necessary vigilance, he took out a signal jammer from his pocket and put it on the table, looking at Ye Hao lightly.

Ye Hao smiled: "Mr. Jiao, this is a gift I brought to you, please accept it." After drinking, he pushed the safe in front of Jiao Jiangbo.

Jiao Jiangbo glanced at Ye Hao lightly, picked up the safe and got up to leave.

"Wait......"

"What else does Mr. Robert have to order?" Jiao Jiangbo looked at Ye Hao meaningfully.

Ye Hao didn't care about Jiao Jiangbo's tone at all: "Mr. Jiao, this should be our third cooperation, of course, I also hope to continue to cooperate." Therefore, in order for the two of us to be able to cooperate happily, I think it is necessary to talk about the conditions, what do you say?"

"Mr. Robert......"

Ye Hao waved his hand to stop Jiao Jiangbo's words, and continued: "Please listen to me first, I believe that Mr. Jiao should understand the value of the things I handed over to you." In order to continue working together, I have only one request, and that is cash. I only accept cash! This time the gift is still given, next time it will be a suggestion? Mr. Jiao can discuss it with his family. We will meet here again in three days, and I hope that Mr. Jiao can give me a satisfactory answer. After speaking, he signaled Jiao Jiangbo to leave.

Jiao Jiangbo frowned and looked at Ye Hao, dissatisfied with Ye Hao's behavior of taking the initiative, but he didn't say anything, just asked, "Mr. Robert means to trade in three days?"

"Well, Mr. Jiao has cash ready. Ye Hao nodded.

Jiao Jiangbo didn't say anything more, picked up the signal jammer on the table, opened the door of the box, and left Nanjiang's house under the protection of the field agents.

————————————————————

Three days later, Jiao Jiangbo received feedback from China.

This time, the information that Ye Hao gave him was about radar technology.

Over the past few decades, phased array antennas have dramatically improved the performance of traditional radars. Edged electronic beam control takes advantage of the performance advantages of phased array antennas and introduces edged control, which greatly reduces the maintenance cost and failure rate of mechanically controlled radar antennas while increasing the speed and accuracy of radar scanning.

In the new AESA, the T/R modules can be configured to work independently or in groups. This support generates multiple beams operating with different frequencies, thus realizing the dynamic and intelligent application of scanning resources, and this highly adaptable structure helps to reduce the probability of interception.

In order to reduce the size, weight, power consumption, cost, and scalability of AESA radar, researchers in the United States have developed a new state of the art of sparse arrays. These arrays are combined to form larger virtual arrays using multiple-input, multiple-output (MIMO) technologies similar to those developed for 5G wireless communications.

MIMO radar uses multiple independent transmitting and receiving antennas to achieve spatial diversity, and applies algorithms to calculate radar reflection and obtain composite resolution. These antenna systems can also operate simultaneously on different frequencies or in a hospitality band without interference with each other, further improving the ability to identify real targets under radar clutter.

Compared with phased array antennas, MIMO radar has better performance than traditional phased array systems, although it consumes more energy.

Raytheon, a U.S. Department of Defense arms supplier, has developed a new material for its radar, gallium nitride. This new material has extreme physical stability, radiation resistance, high-voltage survivability, and very high thermal stability. As a result, GaN electronics exhibit amazing power density and high power-added efficiency compared to other solid-state technologies. When used in low-noise amplifiers, GaN also has good robust characteristics, providing a sensitive receiver technology that is not easily disturbed, corrupted, or affected by limited dynamic range.

The information provided by Ye Hao is the full production process of gallium nitride, as well as the structure diagram of MIMO radar. With these data, Huaxia's radar technology will reach a new level, and the time saved will be more than ten years.

Huaxia didn't care about Ye Hao's requirements, because with Huaxia's current national strength, the problems that could be solved with money were not a problem. There is only what money can't buy, and there is no technology that can't be bought.

Coupled with the three techniques provided by Ye Hao in a row, it gave Huaxia a great shock, and it is said that even the Great Elder heard about it. China believes that Ye Hao and the team behind him have considerable energy in the United States. Since they want to sell some key technologies, there is no reason to refuse, as long as it is worth the money, Huaxia is not afraid to spend money.

Therefore, Jiao Jiangbo was given considerable authority to decide for himself whether to trade on the spot.

Huaxia is not worried at all, Ye Hao will use some expired or even fake technologies to deceive, and the team that can obtain the core technology of the United States will be a fraud gang?
