Annotation: The article is dedicated to research of electromagnetic field penetration into shielding enclosure through technological aperture. The simulation is performed by the finite-difference time-domain method. Next types of electromagnetic waves polarization are observed: circular, horizontal, vertical and elliptic. A criterion of the penetration is based on the value of electric component of the field in the center of enclosure. Calculations are done depending on the frequency of the field and the angle of propagation. Obtained results demonstrate that in several conditions penetration of the filled with circular polarization prevails on other types of polarization.
