Abstract: In this work a novel TE10–TE20 mode converter for rectangular waveguide (RW) is presented. The proposed structure is conceived as a device that can be inserted in an empty straight section ...

Abstract: The complex dispersion diagram of an antisymmetrically biased ferrite-filled rectangular waveguide (RWG) is investigated, revealing that the waveguide supports a band-limited unidirectional ...

5G base stations rely on phased arrays to steer signals and increase data rates. Beam steering circuits, however, consume power. Using waveguides could reduce energy consumption in base stations.

Researchers have developed a new class of integrated photonic devices -- 'leaky-wave metasurfaces' -- that convert light initially confined in an optical waveguide to an arbitrary optical pattern in ...

Due to the power capacity limitation of the rotary joint, mechanical scanning radars are limited to use high-power microwave sources to improve their performance furthermore. To solve this problem, an ...

A leaky-wave antenna (LWA) realizes radiation of travelling wave along guiding structures. Periodic modulation is an effective approach to turn non-radiating modes into radiating modes. A ...

Part 1 of this FAQ looked at the context and the need for waveguides; Part 2 looks at the implementation and available components. Q: What standard waveguide are available? A: There are thousands of ...

A waveguide is an optical structure that directs the electromagnetic waves of an optical spectrum. Some of the most common types of waveguides include rectangular waveguides and optical fibers. In ...

A kind of plasmonic open waveguide, which is a periodic subwavelength metallic Domino array, is investigated both theoretically and experimentally in this paper. Based on the guiding mechanism of ...
