Multi-beam antennas are critical components in future terrestrial and non-terrestrial wireless
communications networks. The multiple beams produced by these antennas will enable …

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

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

In this letter, we propose and study a 2-D glide-symmetric dielectric periodic structure. We
demonstrate that glide symmetry broadens the bandwidth of operation and achieves lower …

In this letter, we present the experimental validation of a-band Luneburg lens antenna based
on a novel cost-effective metasurface. The metasurface is composed of a parallel plate …

A Huygens' metasurface with unit cells of glide symmetric I-shape metal strips is proposed
for a high-efficiency metalens antenna. The proposed unit cell achieves more than 98.6 …

An anisotropic unit cell based on glide symmetry is proposed for tailoring a metasurface that
engineers an optically transformed Luneburg lens. Thanks to the optical transformation, the …

Many frequency-selective surface (FSS) structures are based on the use of a single periodic
array of slot/apertures in a conducting sheet embedded in a layered medium. However, it is …

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

This article investigates the dispersion properties of metasurfaces with hexagonal lattices,
including potential higher symmetric configurations. We explore the relationships between …
