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

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

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 …

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, two novel efficient leaky-wave antennas (LWAs) with stable radiation patterns
operating in the 60 GHz band are proposed. The LWAs are implemented in groove-gap …

A fully metallic glide-symmetric waveguide filter with transmission in Ka-band and
attenuation at its second harmonic is proposed. The filter is low-loss and cost-effective for …

In this article, we present two efficient leaky-wave antennas (LWAs) with stable radiation
pattern, operating at 60 GHz. Both antennas exhibit attractive properties such as significantly …

Mushroom-type electromagnetic bandgap (EBG) structures are known to operate as high-
impedance surfaces at low-frequency bands. They are broadly used in the microwave …

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