Abstract: A millimeter-wave bandpass filter for Ka-band applications is proposed, which uses a rectangular waveguide and spoof surface plasmon polariton (SSPP) with a notched band. This filter ...

Abstract: This paper proposes a sub-THz Riblet coupler based on the empty substrate integrated waveguide (ESIW) and a transition structure between ESIW and a WR-3 rectangular waveguide. The ESIW is ...

Rectangular waveguide is the most common type of transmission line used in microwave communication. It is a metallic transmission line ideally suitable for microwave frequencies and is employed to ...

For the system noise temperature calibration of the K/Q/W triple-band cryogenic receiver on Tianma Radio Telescope (TMRT), a design of W-band eight-hole waveguide directional coupler is proposed in ...

Take a look at an in-depth analysis of rectangular and double-ridge waveguides, highlighting their design, advantages, applications, and power-handling considerations in RF systems. Rectangular ...

In this test case, the scattering parameters (reflection and transmission) are calculated for a rectangular waveguide using Elmer, an open source multiphysical simulation software. The waveguide is ...

The first theoretical models of the propagation of an electromagnetic field in a waveguide date back to the second half of the 19th century (Hertz, Debye, Rayleigh). The technological fallout for long ...
