WEAKLY REFLECTING THIN ABSORBING METASURFACES TO REDUCE REFLECTION FROM METALLIC/METALLIZED OBJECTS OF COMPLEX SHAPE IN THE MICROWAVE RANGE
Description:
For effective absorption of radiation, it is necessary to ensure that destructive interference occurs inside the structure of the metasurface array itself, while the transmitted radiation will be greatly attenuated, and the energy of this radiation will be dissipated by heat generation.
Field of application:
The results of the study can be used in the design of devices and materials for shielding metal or metallized objects of complex shape, the development of interrupters of fiber-optic systems, infrared radiation indicators, as well as devices for spatial modulation of infrared radiation, in the development of new types of electrodynamic materials based on the concept of the studied metasurfaces, for example, frequency-selective and polarization reflectors, interrupters, radiation polarization converters.
It is planned to develop the project in the direction of creating a radiation absorber material, frequency tunable on the basis of omega elements or alternative structures. It is worth noting the prospect of creating detection devices (sensors) based on this metamaterial, taking into account the fact that the absorbed electromagnetic energy eventually passes into dissipated thermal radiation.
