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 ...

Abstract: A novel fully micromachined coplanar waveguide (CPW) to rectangular waveguide transition is presented in this paper. A metalized probe is adopted to couple the signal from the CPW to the ...

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 ...

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 ...

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 ...

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 ...

Waveguides generate digital images directly in the field of vision and enable smart glasses such as the Meta Ray-Ban. We explain the technology behind them. Waveguides, as they are known in German, ...

Augmented Reality (AR) glasses use waveguide technology to project virtual pictures onto the real world, providing immersive experiences in healthcare, manufacturing, and defense. Achieving ...
