Synthesis of high-frequency wave filters and transformers for communications systems

The new theory of wave filters and their synthesis is presented for the first time on the basis of a modeling method using circuit models made exclusively from the first order phase parts. The method is applicable for the synthesis of the filters on transmitting line pieces and may be used for the design of microwave, acoustic, optical and mechanical filters with Butterworth, Chebyshev, elliptic and any other characteristics.
