Mosaic frequency selective surface with wideband response for the optically transparent and absorber applications
This study investigated the performance of a Mosaic Frequency Selective Surface (MFSS) structure for two different applications: optical transparency and absorber. The MFSS for optical transparency application is comprised of a polycarbonate substrate with permittivity, varepsilon_{r} of 2.9, and th...
