Abstract

Polarization is a parameter that plays a pivotal role in communication during transmission and reception of signals. Presence of lumped elements along a signal path or around a region of interaction of incoming waves with surface may trigger distortion in the signals, leading to loss or damage of information. Generally, electronic lumped components are used but their functional abilities are limited during practical operations. The present disclosure addresses the unresolved problems of the conventional system by providing a system and method for real time multi-frequency operation using metasurface-based mechanically controlled tunable polarization conversion. In the present disclosure, a multi-band polarization converter design is provided whose operational parameters including (i) bands of operation, (ii) bandwidth, and (iii) number of bands are controlled together by modulating an air-gap of a reflective unit cell of a two-dimensional array structure of a metasurface using a motorized mechanical arrangement.
