A novel broadband microwave absorber based on a lossy Electromagnetic Bandgap (EBG) structure is presented, and the absorption performance is examined. The proposed absorber includes a lossy EBG surface with the specific sheet resistance, which replaces the conventional resistive sheet of Salisbury screen. The measured result for the absorber showing a(More)
The microwave absorbers are extensively applied in many military and civilian applications for stealth, camouflage, radar cross section (RCS) reduction, and improvement purpose of the inroom EM wave environment in anechoic chambers and indoor wireless LAN area. Although the absorbers can be categorized to many types, it is well known that more useful device(More)
