Parametric studies on hexagonal ring based aperture and patch type curved frequency selective surface

Simulated and experimental investigations on hexagonal ring based aperture and patch type semi cylindrical curved frequency selective surfaces (FSSs) have been presented. Simulated and experimental results are in good agreement. Also, the parametric studies have been done for patch and aperture type Curved FSSs. Curved FSS structures are recently being investigated to design radome or nose of fighter aeroplane. This study will help the researchers to design curved frequency selective structures with both band pass and band stop properties.
