A hybrid method that combines the results of a commercial simulator with analytical
postprocessing is discussed and used to compute the dispersion diagrams of periodic …

Here, we propose a fully metallic implementation of a Luneburg lens operating at Ka-band
with potential use for 5G communications. The lens is implemented with a parallel plate that …

Metasurfaces are thin two-dimensional metamaterial layers that allow or inhibit the
propagation of electromagnetic waves in desired directions. For example, metasurfaces …

We present a novel electromagnetic bandgap (EBG) structure, which can be used to
manufacture low-cost waveguiding structures at high frequencies. The unit cell of the …

The behavior of a glide-symmetric holey periodic structure as electromagnetic bandgap is
studied in this letter. A number of numerical simulations have been carried out in order to …

The presence of glide symmetries in periodic structures can introduce beneficial
modifications in their electromagnetic properties. The difference between glide and non …

We study the wave propagation between two glide-symmetric metallic plates drilled with
periodic rectangular holes. A mode-matching method is proposed in order to derive …

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 …

The dispersion characteristics of a glide-symmetric holey periodic surface are investigated,
with special emphasis on a detailed study of its stopbands. The unit cell is modeled as a …

In this article, a number of guiding structures are proposed which take advantage of higher
symmetries to vastly reduce the dispersion. These higher symmetries are obtained by …
