Polarization insensitivity characterization of dual-band perfect metamaterial absorber for K band sensing applications

Abstract Polarization insensitive metamaterial absorbers (MA) are currently very attractive due to their unique absorption properties at different polarization angles. As a result, this type of absorber is widely used in sensing, imaging, energy harvesting, etc. This paper presents the design and ch...
