Goal of the methodical instructions is to help students during independent study theoretical principles of discipline "Engineering Electrodynamics", part 1 – theoretical foundations of electromagnetics and in the performance of individual tasks and laboratory work. The description of the laboratory work includes along with methodical recommendations on theoretical and experimental research (study) of the basic processes in a microwave path, measuring methods of their parameters and performances. Laboratory work named research of operating modes of waveguide transmission line. Methodical instructions are intended for students of full-time and part-time forms of education on telecommunications training area.
