Abstract

This paper discusses the effect of edge diffraction on radiation intensity in the projected geometric shadow of a protective shield. We also discuss the use of the Cornu spiral to determine the energy flux density of radiation, and this procedure was adapted to perform engineering calculations. Approximate equations are provided for calculation of the basic electromagnetic field parameters in the case where the radiation is diffracted by the edge of a semi-infinite plane, and the radiation intensity behind the protective shield was estimated using this procedure. The practical value of the procedure proposed in this paper is that it enables the dimensions of the protective shield to be determined without complex calculations using specialized software.
