ELECTROMAGNETIC WAVE ABSORBER

摘要

FIELD: physics. ^ SUBSTANCE: invention relates to radar absorbing coatings and absorbers used in antenna structures and antenna systems for optimising radio engineering characteristics and reducing the effect of close metallic or dielectric surfaces. Plates of single-layer flat radar absorbing materials or radar absorbing coatings are perforated and the degree of perforation is proportional to the required absorption attenuation coefficient. ^ EFFECT: weakening absorption of electromagnetic waves without considerable material and time expenses.
