In this article, we study the wave propagation in a metallic parallel-plate structure with glide-
symmetric elliptical holes. To perform this study, we derived a mode-matching technique …

This article analyzes thoroughly the dispersion and filtering features of periodic holey
waveguides in the millimeter-wave frequency range. Two structures are mainly studied …

Higher symmetries frequently amaze human beings because of the illusions and incredible
landscapes such symmetries can produce. For example, imagine the unearthly pictures of …

Glide symmetry offers new degrees of freedom to engineer the properties of periodic
structures, and thus it has been exploited in various electromagnetic structures. However, so …

In this article, we demonstrate how twist symmetries can be employed in the design of flat
lenses. A lens design is proposed, consisting of 13 perforated metallic sheets separated by …

This paper studies wave propagation in a periodic parallel-plate waveguide with equilateral
triangular holes. A mode-matching method is implemented to analyze the dispersion …

We discuss here under which conditions a periodic line with a twist-symmetric shape can be
replaced by an equivalent non-twist symmetric structure having the same dispersive …

We propose a circular twist-symmetric dielectric waveguide that is polarization-selective. In
the practical implementation of optical fibers, a selective circular polarization is more …

This work presents a new configuration to create glide-symmetric structures in a single
plane, which facilitates fabrication and avoids alignment problems in the assembly process …

A mode-matching formulation is presented and used to analyze the dispersion properties of
twist-symmetric transmission lines. The structures are coaxial lines periodically loaded with …
