How to design Metamaterial in CST

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 . Given unit cell  For the Complete Designing watch video: If you are interested to calculate using an equation apply the following equation⏬ Equation:      ...

How to Design || A broadband cross-polarization conversion anisotropic metasurface based on multiple plasmon resonances

  A broadband cross-polarization conversion anisotropic metasurface  based on multiple plasmon resonances. A compact broadband cross-polarization conversion metasurface functioning in the microwave regime is realized and experimentally demonstrated. The metasurface consists of a two-dimensional periodic arrangement of anisotropic double-slit split-ring-resonator-based unit cells printed on top of a dielectric substrate, backed by metallic cladding. The proposed metasurface converts an x- or y-polarized wave into its orthogonal polarization over a fractional bandwidth of 100% from 5-15 GHz, both for normal as well as oblique incidence. Moreover, the sub-wavelength unit-cell size, thin dielectric substrate, and unique unit-cell design collectively make the response of the metasurface the same for both polarizations and insensitive to the incidence angle. The designed structure is fabricated and tested. The measurement and simulation results are found to be consistent with each o...

An Angularly Stable Tri-band Reflective Cross-polarization Conversion Anisotropic Metamaterial

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 ...
