Long-wave infrared birefringent crystals are essential materials in infrared optical applications in fields such as infrared ...

For example, radio waves are transmitted by walls - this explains why these signals can be detected by radios inside a person's house. However, visible light rays are absorbed by walls ...

Newly published research demonstrates a novel way of generating phonon-polaritons by making electrons collide with crystal lattice structures. The discovery paves the way for cheaper, smaller ...

such as infrared and UV waves. For example, mobile phones use microwave radiation for communication, and infrared cameras are utilized for night vision. Terahertz technology utilizes a type of ...
