The lasers are not immune to jamming


In the world of the military, the laser-systems are very popular because they are immune to the jammer system. The fact is that LIDAR (Light Detection and Ranging) -based systems can jam by giving the laser system false laser echoes. Jamming the laser-based rangefinder is quite easy. The laser detector can be jam by pointing it with another laser and that radiation will cause that the system will get the wrong values, and the warhead of the missile will translate the strong radiation echo that the impact is coming. 

In future systems, the counter radiation can send by using the same frequency what has the same frequency as the laser radiation that is sent from the LIDAR-system. When those laser rays will travel through the LIDAR-radiation it will polarize the radiation. And that thing will twist the radiation waves of the LIDAR system. 

If the laser rangefinder is pointed by another laser that causes the echo what the system detects is too strong. And this kind of way to use the counter radiation can cause that the missile will explode too early. In this case to the laser will target another laser, which will disturb the aiming and ranging system. 

In the modern cruise missile, the LIDAR-based systems are in use at altimeters and targeting systems. In those systems the echo, what the LIDAR-system will get will be twisted. The twisting of those radiation echoes can do by using dust, which absorbs part of that radiation or making a hologram, or sending another laser ray through the LIDAR-system's laser radiation. 

If the LIDAR-based altimeter gets twisted echoes, that can cause that the thing like a cruise missile will rise too high. If the echo is too strong that thing will cause the computer of the missile to think that the missile is flying too low. And if the echo is too weak the system translates that the missile or drone flies too low. And if the change of altitude is too down and flight altitude is about 100 meters, the drone can crash immediately.

Plasmonic waves can make new waves in quantum technology.

"LSU researchers have made a significant discovery related to the fundamental properties and behavior of plasmonic waves, which can lead ot the development of more sensitive and robust quantum technologies. Credit: LSU" (ScitechDaily, Plasmonics Breakthrough Unleashes New Era of Quantum Technologies) Plasmonic waves in the quantum gas are the next-generation tools. The plasmonic wave is quite similar to radio waves. Or, rather say it, a combination of acoustic waves and electromagnetic waves. Quantum gas is an atom group. In those atom groups, temperature and pressure are extremely low.  The distance of atoms is long. And when an electromagnetic system can pump energy to those atoms. But the thing in quantum gas is that the atoms also make physical movements like soundwaves. It's possible. To create quantum gas using monoatomic ions like ionized noble gas. In those systems, positive (or negative) atoms push each other away.  When the box is filled with quantum gas and som

Metamaterials can change their properties in an electric- or electro-optical field.

"Researchers have created a novel metamaterial that can dynamically tune its shape and properties in real-time, offering unprecedented adaptability for applications in robotics and smart materials. This development bridges the gap between current materials and the adaptability seen in nature, paving the way for the future of adaptive technologies. Credit: UNIST" (ScitechDaily, Metamaterial Magic: Scientists Develop New Material That Can Dynamically Tune Its Shape and Mechanical Properties in Real-Time) Metamaterials can change their properties in an electric- or electro-optical field.  An electro-optical activator can also be an IR state, which means. The metamorphosis in the material can thermally activate.  AI is the ultimate tool for metamaterial research. Metamaterials are nanotechnical- or quantum technical tools that can change their properties, like reflection or state from solid to liquid when the electric or optical effect hits that material.
