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 ...

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.

Abstract: In this letter, we propose a method to realize rectangular waveguide mode to spoof surface plasmon polaritons (SSPP) mode conversion using phase gradient metasurface (PGM). By applying a PGM ...

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 ...

Sketch of the DFG process in a rectangular AlGaAs waveguide fully embedded in a SiO 2 cladding. An intense pump (blue) and a weak seed (green) at the waveguide input interact inside the waveguide, ...

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 ...

We experimentally demonstrate a nanoscale mode converter that performs coupling between the first two transverse electric-like modes of a silicon-on-insulator waveguide. The device operates by ...

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 ...
