Integrated software package for synthesis, analysis and optimization of frequency-selective devices of millimeter and centimeter waves

The state of the art of theory and practice of signal frequency selection in the millimeter and centimeter wave ranges can be described from one hand as going to more sophisticated schemes of filter building and from another hand, especially in millimeter waves, by extensive usage of practically non-tuning configurations. The first direction as well as the second one is based on the powerful software and on modern production processes, that provide minimal tolerances. Below is a summary of the results that have been obtained in IRE NASU regarding to one of this two sides of filter problems: the short description of the set of software packages for the synthesis and analysis of low-pass (LPF), wide-band and narrow-band band-pass (BPF), and band-stop (BSF) rejection waveguide filters.
