This article applies an in-house generalized ray-tracing (RT) model to efficiently compute
both the radiation pattern and the efficiency of geodesic lenses with nonrotationally …

The millimeter-wave (mmWave) and sub-terahertz (sub-THz) bands have received much
attention in recent years for wireless communication and high-resolution imaging radar …

This article delves into the industrial evolution of lens antennas for future millimeter-wave
and sub-THz radio access applications. Here, we address the potential advantages of …

This paper introduces an all-metal series dual-fed continuous transverse stub (CTS) array
that enables multi-beam operation at K-band. This capability is obtained by utilizing a …

The geodesic Luneburg lens has been revisited as a suitable solution for applications
requiring directive beams in the millimeter waveband. Among its advantages, its rotational …

Additive manufacturing (AM) is growing as a key technology for the miniaturization and
integration of microwave components. Among several AM processes, laser powder-bed …

We propose a method to extract the equivalent material parameters and circuit parameters
for all-metallic tensor metamaterials. The metamaterials consist of an arrangement of sub …

This paper presents a wide-angle partial Maxwell Fish-Eye (PMFE) lens antenna for W-band
millimeter-wave communication, which is realized by alumina 3D printing using lithography …

This paper presents a single offset-reflector antenna in a parallel plate waveguide (PPW),
which is capable of radiating two orthogonal linear polarizations with high gain at W-band …

This article suggests a new waveguide design that utilizes a “walled” architecture. Instead of
relying on conventional gap waveguide structures to create electronic bandgaps and …
