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 ...

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: The dielectric slab rectangular waveguide (DSRW) has been widely studied and used for increasing the single-mode bandwidth (BW) of rectangular waveguides. This work presents a DSRW for ...

Last month, this column discussed some of the fundamental concepts of selecting coaxial transmission lines. That included low-power flexible lines as well as some issues involving high-power rigid ...

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 ...

For most design engineers, study of waveguide technology ended when they got their last degree. The only time waveguide comes up is to use it as a last resort in applications such as millimeter-wave ...
