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, a novel cost-effective flange is proposed to prevent the leakage created by
undesired air gaps between flanges of two mating waveguides. The cause of an undesired …

This article presents a parallel-plate lens beamformer for continuous wide-angle scanning.
The design is based on a compact dual-lens system with extended scanning range and is …

A fully metallic glide-symmetric waveguide filter with transmission in Ka-band and
attenuation at its second harmonic is proposed. The filter is low-loss and cost-effective for …

For terahertz systems, rectangular waveguide is an ideal low loss medium for
interconnectivity and the construction of passive circuits. A drawback when manufacturing …

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 paper presents a novel micromachining process to fabricate a 140 GHz planar antenna
based on gap waveguide technology to be used in the next-generation backhauling links …

Gap waveguide has recently been proposed as a low-loss and low-cost technology for
millimeter-wave components. The main advantage of the gap waveguide technology is that …

Higher symmetries frequently amaze human beings because of the illusions and incredible
landscapes such symmetries can produce. For example, imagine the unearthly pictures of …

A novel real-time rotatable rectangular waveguide twist is presented in this letter. The
proposed waveguide twist is based on the contactless waveguide flange technique. The …
