Abstract: In this contribution, an Integral Equation (IE) formulation is proposed for the analysis of microwave circuits, based on the junction of two different rectangular waveguides coupled by an ...

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: 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 ...

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 ...

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 ...

5G base stations rely on phased arrays to steer signals and increase data rates. Beam steering circuits, however, consume power. Using waveguides could reduce energy consumption in base stations.
