With the monotonic increasing demand of the higher bandwidth for the next generation
wireless communication system, the extension of the operating frequency of the …

Leaky waves have been among the most active areas of research in microwave engineering
over the second half of the 20th century. They have been shown to dominate the near-field …

Due to exponential growth in wireless communication in the last decade, which continues
towards future applications, mm-wave has shown tremendous potential and has been …

New communications systems require high-speed data transfer and need high frequency,
wideband, and directive antennas. Leaky-wave antennas are a desirable type of antennas …

We introduce a novel antenna concept suitable for future integrated arrays at terahertz
frequencies. The antenna consists of an extended hemispherical lens antenna fed by a …

Aims. Future actively cooled space-borne observatories for the far-infrared, loosely defined
as a 1–10 THz band, can potentially reach a sensitivity limited only by background radiation …

In the last decade, a technique termed transformation optics has been developed for the
design of novel electromagnetic devices. This method defines the exact modification of …

High-gain lens antennas with a subwavelength thickness that radiate linearly and circularly
polarized waves are reported. The lens antennas are fed with a planar, leaky radial …

Dielectric lens antennas are attracting a renewed interest for millimeter-and submillimeter-
wave applications where they become compact, especially for configurations with integrated …

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 …
