An Angularly Stable Tri-band Reflective Cross-polarization  Conversion Anisotropic Metamaterial A tri-band microwave cross-polarization conversion (CPC) metasurface is designed and simulated. The metasurface consists of a split-ring-resonator (SRRs) with two splits placed within perpendicular sides of the SRR and designed on an FR4 dielectric substrate backed by a metallic ground plane. An efficient CPC, both for normal as well as for oblique incidence, is achieved. This multi-band polarization conversion results from multiple plasmonic resonances occurring at three neighboring frequencies. Owing to sub-wavelength unit cell size, thin dielectric substrate, and optimized structure of the SRR, the response of the metasurface is independent of the incidence angle of the incoming wave which makes it a potential candidate for many practical applications. introduction Control and manipulation of the polarization state of electromagnetic waves have always been ...

An Ultra-thin Wide-Angle Cross Polarization Conversion Metasurface   In this article, a bandwidth-enhanced metasurface  has been designed using a single circular split ring as a unit cell on  the top surface of a metal-backed FR4 substrate. The structure behaves as a cross-polarization conversion (CPC) metasurface over full width at half maxima (FWHM) bandwidth of 12.94 GHz ranging from 9.44 GHz to 22.38 GHz. The proposed CPC metasurface maintains bandwidth enhancement up to 45° incident angles under both TE and TM polarizations. The structure is ultra-thin (~ /11.4 with respect to the center  frequency) in nature.   Due to its compact nature, studies on metasurface have  become a hot topic of research as its application toward  frequency selective surface (FSS). These FSS structures have been proposed as filters, absorbers, polarizers, etc. Recently, metasurface-based cross-polarization conversion (CPC) structures ...

Meta-Material simulation files Metamaterial absorbers (MMA) have recently become a new focus of research to develop a  perfect resonant system for MMA. MMA is designed to effectively absorb EM radiation. Land  yet used a combination of the electrical resonator and cut wire to test this unusual effect for  the first time. MMA has different properties and offers excellent features including near-unit  absorption, ultra-thin thickness, large incidence angles, low cost, and insensitivity to  polarization, making it ideal for antenna designs, reduction of radar cross section (RCS) in  stealth technology, photodetectors by enhancing absorption in solar photovoltaic and thermophotovoltaic cells to improve the performance and also in wireless communication .
