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 …

Recently, there has been growing interest in the use of metamaterial (MTM)-based lenses,
also known as metalenses, as innovative antenna technology. Increasingly widespread …

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 …

The gradient-index (GRIN) Luneburg lens antenna offers significant benefits, eg high
aperture efficiency, low-power, minimal cost, wide beam scanning angle and broad …

A novel all-metal graded index Gutman lens is proposed. It exploits an interleaved
metasurface unit-cell with glide symmetry that can provide high values of equivalent …

In this paper, we present a general mode matching formulation to analyze the wave
propagation in glide-symmetric metallic surfaces drilled with periodic holes with an arbitrary …

In this paper, 1-D periodic structures possessing higher symmetries are proposed and
investigated in terms of their dispersion properties. The proposed structures are coaxial lines …

New high-frequency 5G and satellite communication systems require fully-metallic antennas
and electromagnetic components. These components can be implemented with truncated …

This letter presents a novel dual-polarized two-dimensional (2-D) Luneburg lens operated at
millimeter-wave band with a low-profile and planar structure. Based on a dual-mode unit cell …

A phased array antenna (PAA) with wide beam scanning range (BSR) composed of fully
metallic lens antenna subarrays is proposed. Each subarray is designed based on a partial …
