Terahertz systems have a new capacity to manipulate light.

"Researchers have created a new method to generate structured terahertz light beams using programmable spintronic emitters, marking a significant advancement in terahertz technology. This innovation allows for the generation and precise manipulation of light with both spin and orbital angular momentum."(ScitechDaily, Terahertz Breakthrough: New Technique Offers Unprecedented Control Over Light)

New terahertz systems use spintronics to create radiation. The system uses spintronic-based programmable spintronics. And those spintronics have an important role in the new terahertz systems that can open paths to new communication and photonics control.

The system where photons are trapped in the terahertz radiation can be incredibly multi-used. Researchers can use that thing for making new sensors and new communication tools.

Terahertz radiation can make channels that can used to manipulate photons. That thing can used in the new photon-based neural networks, that can sense electromagnetic and even gravity waves with new accuracy. Those systems can make it possible to collect data about gravity waves and their interaction with other radiation types.

Teraherz-radiation is one possibility for the new communication lines. Those kinds of things are important for the 6G and faster communication. The terahertz radiation allows to make more channels for the 6G communication.

That thing makes it a very interesting tool is that the terahertz radiation goes through the walls. That makes this thing a very promising alternative to laser communication. The laser ray will not normally travel through walls. And that limits its use in the wireless network.

"UAB researchers have developed an innovative switch for 6G communications that doubles performance to 120 GHz and reduces energy use, promising enhanced sustainability and efficiency in telecommunications." (ScitechDaily, High-Frequency, Low-Power: Researchers Develop Switch To Revolutionize 6G Communications). It's possible. The 6G network can also use terahertz frequencies. Terahertz frequencies involve more frequencies and more space in that network.

Coherent terahertz or terahertz masers can offer safe and effective communication tools. They can be the new tools for communication in highly populated areas. Terahertz masers can send their data in a coherent package. If the eavesdropper cannot put the antenna in the Terahertz radiation that makes communication safer, because the eavesdropper must precisely know, where the message travels.

Coherent terahertz radiation allows to send multiple messages in the same way as lasers. The messages travel like laser beams, but terahertz radiation uses different frequencies. That means the coherent terahertz radiation can also offer to use bandwidth more effectively than in non-coherent communication. In terahertz technology, the system can send more data if it uses coherent terahertz-based data transport.

Chinese innovations and space lasers are interesting combinations.

(Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft. Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things. In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion. If we th

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful. Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down. The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts. The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
