Antenna designs incorporating metamaterials can improve the radiated power of an antenna. The newest metamaterial antennas radiate as much as 95 percent of an input radio signal. Standard antennas need to be at least half the size of the signal wavelength to operate efficiently. At 300 MHz, for instance, an antenna would need to be half a meter ...
Ansys HFSS (high-frequency structure simulator) is a commercial finite element method solver for electromagnetic (EM) structures from Ansys. [ 1 ] Engineers use Ansys HFSS primarily to design and simulate high-speed, high-frequency electronics in radar systems, communication systems, satellites, ADAS, microchips, printed circuit boards, IoT ...

Metamaterial antennas are a class of antennas that use metamaterials to improve performance. [15] [21] [85] [86] Demonstrations showed that metamaterials could enhance an antenna's radiated power. [15] [87] Materials that can attain negative permeability allow for properties such as small antenna size, high directivity and tunable frequency ...
In terms of antenna design, MSAT introduces an innovative perspective by using metasurfaces and holographic beamforming principles. Unlike traditional three-dimensional metamaterials, which rely on bulky structures and resonant phenomena, MSAT employs metasurfaces characterized by small periodic scatterers and surface thickness relative to the ...
A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. [2] In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the ...
The EM metamaterial as an artificially designed transmission medium, has so far delivered desired responses at frequencies from the microwave through to the near visible. [6] The introduction of a natural semiconductor material within or as part of each metamaterial cell results in a new design flexibility.
Metamaterials Handbook is a two-volume handbook on metamaterials edited by Filippo Capolino professor of electrical engineering in University of California. [1] [2]The series is designed to cover all theory and application topics related to electromagnetic metamaterials.
