On a dispersion curve of a waveguide filled with inhomogeneous substance
Discrete and Continuous Models and Applied Computational Science, 2022 The paper discusses the relationship between the modes traveling along the axis of the waveguide and the standing modes of a cylindrical resonator, and shows how this relationship can be explored using the Sage computer algebra system.

Computation of the Modes of Elliptic Waveguides with a Curvilinear 2D Frequency-Domain Finite-Difference Approach [PDF]
, 2012 A scalar Frequency-Domain Finite-Difference approach to the mode computation of elliptic waveguides is presented. The use of an elliptic cylindrical grid allows us to take exactly into account the curved boundary of the structure and a single mesh has ...

A new rectangular waveguide to coplanar waveguide transition [PDF]
IEEE International Digest on Microwave Symposium, 2002 A novel rectangular-waveguide-to-coplanar-waveguide transition is described. The transition uses a ridge in one of the broad walls of the waveguide and a nonradiating slot in the opposite wall to split and rotate the electromagnetic fields of the rectangular waveguide TE/sub 10/ mode into the coplanar waveguide (CPW) fields.

Multimode synthesis procedure for microwave filters based on thick inductive windows [PDF]
, 1993 For several types of microwave filters for space application it is important to manufacture hardware without tuning elements. For this to be possible, one needs a systematic procedure to codvert ideal elements, such as resonators and impedance inverters,
