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

The introduction of electromagnetic (EM) media with unique field manipulation properties,
collectively labelled as metamaterials, has boosted the interest toward the design, the …

A metamaterial (MTM)-based thin planar lens antenna is proposed for spatial beamforming
and multibeam massive multiple-input multiple-output systems. The antenna consists of a …

Based on a transformation optics method, a flat compact dual-polarized Luneburg lens
antenna is proposed and implemented using the printed-circuit-board-stacked gradient …

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 …

A transformation-optics map** that radially compresses a sphere into a cylindrical slab
with an arbitrary ratio of D/t is proposed to design a flat and thin dual-polarized Luneburg …

This letter presents a method to realize anisotropic two-dimensional designs with wideband
operation. Glide symmetry has been proven to increase the bandwidth and equivalent …

A flat Luneburg lens antenna for Ku-band (12-18 GHz) applications is proposed and
designed using ceramic 3-D printing. Metamaterial structures and transformation optics …

A photonic jet (a terajet at terahertz frequencies) commonly denotes a specific, spatially
localized region in the near field on the front side of a dielectric particle with a diameter …
