FIELD: radio engineering, communication.SUBSTANCE: invention relates to radio engineering, primarily to wideband radar-absorbent coatings. The wideband radar-absorbent coating is made in the form of an absorbing layer of material with dielectric permittivity ?=?'+i·?", magnetic permittivity and refraction index n, deposited on an electromagnetic wave reflecting surface, wherein the absorbing layer is made of material with the real part of the square of the refraction index less than zeroEFFECT: reduced coefficient of reflection of electromagnetic waves in a wide frequency band.5 dwg |
