Reconfigurable intelligent surface (RIS) or Large Intelligent Surface (LIS) creating an intelligent electromagnetic environment for wireless communications

Reconfigurable intelligent surface (RIS)—known also as intelligent reflecting surface (IRS), and large intelligent surface (LIS)—is a programmable structure that can be used to control the propagation of electromagnetic (EM) waves by changing the electric and magnetic properties of the surface. These elements form a low-profile 2D reflecting or transmission array, …

Military RF and Microwave equipments and testing

The electromagnetic spectrum is a series of frequencies ranging from radio waves to microwaves, visible light, X-rays, and gamma rays. As the wavelength of the electromagnetic radiation shortens, the waves have a higher frequency—how quickly electromagnetic waves follow each other—and therefore more energy.   Radiofrequency is a type of electromagnetic …
