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 ...

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 ...

Abstract: In this study, we propose a very simple and easy-to-fabricate transition from a low loss ground coplanar waveguide (GCPW) with sidewalls to rectangular waveguide. It consists of two steps of ...

Abstract: This article proposes a method based on the use of a slotted rectangular waveguide (SRW) for determining the complex permittivity of materials under test (MUTs). Because the slots are ...

This paper proposed an X-band compact efficient rectangular waveguide TE10-circular waveguide TE01 mode converter and conducted its structure design, theoretical analysis, numerical simulation, and ...

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 ...
