Zbl 1107.94016

Summary: The paper is devoted to the analysis of lossy transmission lines termianted by nonlinear \(R\)-loads whose V-I characteristic is approximated by polynomials. By means of fixed-point method conditions for the existence of periodic solutions are formulated. A complete exposition of reducing of the mixed problem for lossy transmission lines to an initial value problemfor a neutral functional differential equation on the boundary is presented. An example demonstrates the applicability of the method. It is shown of how to choose the relations between basic quantities in the process of analysis and design of the transmission lines.
