Design and analysis of frequecy selective surface

The Frequency Selective Surface (FSS) is a two-dimensional periodic array of planar arrays made up of metal patches or aperture units. FSS has the ability to reflect or transmit all incident electromagnetic waves in certain frequency bands, demonstrating exceptionally great frequency selectivity. As...
