Abstract In this paper, an ultra-broadband flexible polarization-insensitive microwave metamaterial absorber is proposed, characterized, and fabricated. To achieve high broadband absorption, a two-layer periodic indium-tin-oxide (ITO) patches array printed on polyethylene terephthalate (PET) dielectric layers used to generate ohmic loss. The simulation results show that the proposed can greater...

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 in those areas is the resonant type m...

Abstract Chalcopyrite semiconductors are widely used as absorbers in thin film solar cells, especially flexible due to their high power conversion efficiency. They also have interesting mechanical properties, making them promising materials for flexible, light, and cells. In this work, we report the first-principle calculations of lattice constant bulk modulus CuInS 2 , CuInSe CuIn(S,Se) absorb...
