This article analyzes a review of recent developments in the field of frequency selective
surface (FSS)-based advanced electromagnetic (EM) structures. FSSs have been the …

Metamaterials are artificially engineered devices that go beyond the properties of
conventional materials in nature. Metamaterials allow for the creation of negative refractive …

Glide-symmetric structures have recently emerged as a smart choice to design planar lenses
and electromagnetic bandgap materials. We discuss here the conditions under which a …

An equivalent circuit (EC) model for the frequency-selective surfaces (FSSs) comprising
anisotropic elements is presented. The periodic surface is initially simulated with an arbitrary …

This paper presents an analytical framework for the study of scattering and diffraction
phenomena in space-time-modulated metallic gratings. Using a Lorentz transformation, it is …

A critical discussion on the computation of the dispersion diagram of electromagnetic
guiding/radiating structures with one-dimensional periodicity using general-purpose …

In this paper, we present analytical models to describe artificial dielectric layers (ADLs),
when a lateral shift between layers is present. The alternate lateral displacement between …

Blazed gratings can reflect an oblique incident wave back in the path of incidence, unlike
mirrors and metal plates that only reflect specular waves. Perfect blazing (and zero specular …

In the study of electromagnetic wave propagation and scattering, researchers have always
faced the dichotomy of dealing directly with Maxwell's equations (and their complicated …

A new framework of scattering analysis of metasurfaces composed of an assemble of
resonant scatterers, with a multistage analysis procedure, is presented. The metasurface …
