Abstract :
An efficient full-wave CAD tool dedicated to coaxial waveguide junctions is presented. The tool is well suited to treat both standard coaxial lines and rectangular-circular coaxial waveguides. The case of offset internal conductors and dielectric filling are contemplated as well. The tool is very efficient and accurate, which allows to be used by iterative optimization procedures for the design of coaxial waveguide components such as low-pass and bandpass filters, and impedance transformers among other structures. Direct coaxial excitations in rectangular waveguides can be characterized as well.
