For single-walled carbon nanotubes (SWCNTs) with a length of 1–50 µm, the surface plasmon-polariton (SPP) resonance is within terahertz frequency range; therefore, SWCNT lattices can be used to design frequency-selective (FSS). A numerical model electromagnetic wave diffraction on two-dimensional periodic lattice described by an integro-differential equation second-order respect current along S...

In this work, a computationally efficient method based on data-driven surrogate models is proposed for the design optimization procedure of Frequency Selective Surface (FSS)-based filtering antenna (Filtenna). A Filtenna acts as module that simultaneously pre-filters unwanted signals, and enhances desired signals at operating frequency. However, due to typically large number variables FSS unit ...

This work presents an eight element array antenna with single layer frequency selective surface (FSS) to obtain high gain. The elements are fed by port. FSS consists of 14x6 unit cells one cell size is 5×5 mm2 having wideband behavior. uses Rogers RT Duroid 5880 substrate and giving very wide bandwidth from 20 GHz 65 GHz, covering mm-wave 5G bands (including 28 38 60 GH...

In this work we propose a system of two frequency-selective surface (FSSs) with an ultra-wide band-stop response for 5G millimeter-wave applications. The analyses are based on the equivalent circuit method, which predicts transmission characteristics plane wave normal and oblique incidence, scattering matrix technique, provides result cascaded structure. geometries used in single-layer FSSs sim...

This paper proposes a novel approach to solve a constrained inverse problem encountered in the design of frequency selective surfaces (FSS's). Due to the many-to-one nonlinear functional relationship between an FSS and its frequency response, there is no closed form solution directly from the given desired frequency response to the corresponding surface. Therefore, to design an FSS for a given ...
