Abstract. This article discusses the distribution of electromagnetic waves in the interior of an electrically sealed enclosure. The side radiation of a microstrip line and its effect on signal propagation are described. The influence of a radio-absorbing material on the behavior of the electromagnetic field in the interior of the case is analyzed. An electrodynamic simulation of a microwave filter (located in a metal case) and an experimental study of the field emitted by it are carried out. The purpose of the work is to describe the effect of a radio–absorbing material on the behavior of electromagnetic waves inside the housing and its effect on the characteristics.
Key words: electromagnetic radiation, field distribution, side radiation, microstrip line, electrodynamic modeling, microwave filter, radio absorbing material.
