This chapter presents Metamaterial (MTM)-based frequency selective surfaces (FSS) and its use as a spatial filter. Initially, a basic idea on the traditional FSS has been given and its fundamentals including working principle have been discussed. Various types and techniques on current state of the art in the FSS designs have also been listed. The disadvantage of traditional FSS and the evolution of traditional FSS to MTM-FSS has been presented. Analysis and design of traditional FSS and MTM-FSS have been performed side by side for better understanding. The comparison is based on frequency response curve, surface current distribution, and angular stability. The parametric analysis of MTM-FSS is also carried. As many of the MTM designs are asymmetrical, similar frequency response is not obtained under both the transverse electric and transverse magnetic incident polarized wave. Therefore, a polarization insensitivity MTM-FSS is also designed and analyzed. The technique used for fabrication and testing of various FSS structures is also listed in one of the sections. Finally, the practical applications where these FSS can be used are listed in this chapter.

摘要

This chapter presents Metamaterial (MTM)-based frequency selective surfaces (FSS) and its use as a spatial filter. Initially, a basic idea on the traditional FSS has been given and its fundamentals including working principle have been discussed. Various types and techniques on current state of the art in the FSS designs have also been listed. The disadvantage of traditional FSS and the evolution of traditional FSS to MTM-FSS has been presented. Analysis and design of traditional FSS and MTM-FSS have been performed side by side for better understanding. The comparison is based on frequency response curve, surface current distribution, and angular stability. The parametric analysis of MTM-FSS is also carried. As many of the MTM designs are asymmetrical, similar frequency response is not obtained under both the transverse electric and transverse magnetic incident polarized wave. Therefore, a polarization insensitivity MTM-FSS is also designed and analyzed. The technique used for fabrication and testing of various FSS structures is also listed in one of the sections. Finally, the practical applications where these FSS can be used are listed in this chapter.
