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 ...

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 ...

When a rectangular waveguide is in free space, the waveguide's characteristics and field distribution for different modes are computed using HFSS software. The analysis is performed for several ...

A rectangular waveguide band-stop filter using electromagnetic crystals (EMXT) surface as the top and bottom walls is presented in this letter. The EMXT surface has a band gap that can prevent ...

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 ...

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 ...

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 ...
