This paper presents a novel concept of half wavelength doubleridged half height rectangular waveguide resonator. The basic design consists of a double-ridged rectangular waveguide placed between two rectangular waveguide WR2300. The resonance frequency, bandwidth, Q factor etc. can be controlled by varying the ridge parameters such as ridge length, width, height, ridge gap width, ridge gap heig...

A design of a compact, easy to fabricate and applicable structure rectangular waveguide TM11 to TE10 mode converter is presented in this paper. The design procedure of the proposed structure can be divided into two parts in sequence. The beginning one is dedicated to the transformation from TM11 to TEM mode using a central conductor, while the second part is the transformation from TEM to TE10 ...

Rectangular waveguide is one of the earliest types of transmission lines. Rectangular waveguide can be produced by hot extrusion process.

The digital waveguide mesh is an extension of the one-dimensional digital waveguide technique. The mesh is used for simulation of twoand three-dimensional wave propagation in musical instruments and acoustic spaces. The rectangular digital waveguide mesh algorithm suffers from direction-dependent dispersion. By using the interpolated mesh, nearly uniform wave propagation characteristics are obt...
