Abstract

The effect of a modified coating, deposited on the surface of foam glass, on the ability to absorb electromagnetic radiation in the high frequency range was studied. It was established that a coating obtained on the basis of a liquid glass composition with ilmenite with 3 μm particles improves the radio absorption characteristics of the foam glass. For 1.5% ilmenite concentration in the coating composition the absorption coefficient of foam glass increases four-fold at 120 GHz and two-fold at 260 GHz compared with uncoated foam glass.
