The investigations were carried out with use of modern methods of applied and computing electrodynsmics, that has allowed to receive results with the high accuary. The advanced methods of optimization have revealed new properties of some elements and blocks: resonators with ridge structure, radiators for multimode resonators raised with the help of microstrip lines, double spirals in circular waveguide, reflecting structures of various types. The results of investigation may be considered as a basic for development and application of the new functional devices based on new properties of considered elements.
