Synthesis of dual-mode filters
This tool is capable to automatically design dual mode filters. The filter structure considered is composed of circular cavities
connected between them through rectangular or cross irises. Additionally, coupling and tuning screws are placed inside each cavity.
It is possible to synthesize four-pole and eight-pole filters, by using the resonant modes TE113 and TE114.
Besides, this design tool is very versatile, and the user can define not only the electromagnetic response specifications, but also
many geometrical parameters like the cavity radius, the iris and screws thickness or the input/output waveguides.
The design process has been fully automatized and achieves very accurate results in short computational times (typically, 15 minutes for a four-pole
filter and 30 minutes for an eight-pole filter, measured in a standard PC).
