Antennas for future communication systems are required to be highly directive and steerable
to compensate for the high path loss in the millimeter-wave band. In this work, we propose a …

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 …

This article describes a detailed procedure that allows for a time-efficient design of fully
metallic geodesic H-plane horn antennas using an in-house ray-tracing method together …

A domain wall separating two different topological phases of the same crystal can support
the propagation of backscattering-immune guided waves. In valley-Hall and quantum-Hall …

In this communication, we propose glide-symmetric double-layer (DL) spoof surface
plasmon polaritons (SSPPs) structures for controlling the field confinement of SSPPs to …

Antennas in emerging millimeter-wave (mm-wave) applications are often required to have
low losses and produce a steerable directive beam. These properties are achievable with …

A systematic and efficient multimodal transfer-matrix approach is proposed for the
comprehensive Bloch analysis of general 1-D/2-D/3-D periodic structures. We provide a …

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 …

A dual wideband antenna with a large beam steering angle through endfire radiation and
frequency scanning radiation in each band is proposed for the first time. The antenna utilizes …
