Description
My research is focused on the periodic structures and their applications to the microwave absorbers and antennas design. During the recent years I have involved in the design and development of:
- wideband and high gain antenna using multilayer partially reflective structures (PRS)
- embroidered PRS antenna
- frequency selective radome absorber (radome that has special characteristics: reflective at lower frequency, transmissive at the antenna operational frequency, and absorptive at higher frequency)
- ultrathin absorber for narrowband application using periodic resonant (metasurface) structure
- thin 3D absorber for wideband application using periodic lossy non-metallic structure
