A convoluted frequency selective surface (FSS) is proposed to provide the unit cell
dimension as small as 4.84% of the free space wavelength at resonant frequency. The FSS …

A simple and accurate approach for computing the effective permittivity of metasurfaces
embedded within arbitrary stratified media is presented. The proposed model provides …

This paper proposes a novel reconfigurable frequency selective surface (FSS) structure for
ultra-wide band (UWB) and multi-band applications. The proposed structure is a simple …

This communication extends a previously reported analytical circuit that models the plane
wave scattering by 2-D arrays of planar patches/apertures embedded in a layered media. In …

A frequency selective surface (FSS) structure with geometrically separable meander-line
inductors (MLIs) and parallel-plate capacitors (PPCs) is proposed. For this FSS structure, the …

This work presents a fractal design methodology for frequency selective surfaces (FSSs)
with Peano pre‐fractal patch elements. The proposed FSS structures are composed of …

Coupled complementary metasurfaces (CCMTS) exhibit a passband whose frequency is
several times lower than that of the individual metasurface (MTS) passband frequency. In …

A 2-D periodic array of annular apertures (or ring slots) is studied using an accurate circuit
model. The model accounts for distributed and dynamic effects associated with the excitation …

A new procedure to synthesis three unknown dimensions of a square loop frequency
selective surface SL-FSS (periodicity, width and the gap between loops) is presented. SL …

Resonant frequency tunable range is an important character for active frequency selective
surfaces (AFSSs), especially when building electronically steerable antennas based on …
