[EN] This communication describes a multimode equivalent network
(MEN) representation of a finite array of open-ended lossless
waveguides on an infinite ground plane. The derivation is based on an
integral equation ...
The insertion of vertical slabs in a metallic rectangular waveguide distorts the power distribution of the waveguide, producing new modes and modifying the existing ones. The resulting waveguide, known as E-plane loaded ...

Cylindrical near-field measurement systems are being widely demanded, especially for imaging applications at millimeter-wave frequencies. One of their most important drawbacks is the long time required to perform a full ...
A compact twist to connect a ridge-gap waveguide and a groove-gap waveguide in the Ka-band is presented. Measured insertion loss for a single twist is around 0.5 dB between 37.5 and 39 GHz. Return loss for a double twist ...
