Rafael Goncalves Licursi de Mello: Metasurface-Driven Electronic Warfare, Gebunden

Klappentext

"Metasurfaces are the two-dimensional version of metamaterials, which are artificially engineered structures that can provide electromagnetic properties not readily found in nature. In satellite communications, metasurfaces can be used to dynamically steer the beam of ground stations allowing for a real-time tracking of satellites in low-Earth orbit, which moves fast in relation to the Earth's surface. Another example is the 6G technology that will use metasurfaces to collect signals in the environment and focus on specific users dynamically, optimizing the data link wherever we are in the cities. Besides that, metasurface also allows the creation of multiband reflectors that enable low-profile, high-gain, directive antennas that cover several standards of communication at the same time, for instance, 5G/4G/Wi-Fi 2.4 / 5/6E."--
