Radar absorbing combinatorial metamaterial based on silicon carbide/carbon foam material embedded with split square ring metal

A broadband radar absorbing combinatorial foam metamaterial (CFMM) was developed and evaluated via simulation and experimentation. CFMM was constructed using silicon carbide/carbon (SiC/C) foam material, a FR4 dielectric material, and a metal pattern. The SiC/C foam material was prepared using a tem...
