Abstract:

Electromagnetic radiation arising from the operation of microwave electronic devices creates significant interference reduces the accuracy of measurement and electromagnetic compatibility of equipment. High frequency radiation has a negative impact not only directly on human being, but also on the operation of the various devices. Therefore, the current studies are aimed at developing radar absorbing materials effective in a wide range of frequencies. Promising in this direction are lightweight materials with high porosity such as foamed glass, which has the ability to reduce the level of reflected and transmitted electromagnetic radiation. However, the effectiveness of radar absorption foam glass inferior to some types of absorbers, so work is underway on modification of foam glass by introducing into its composition of various additives. This paper is devoted to comparison of the absorption capacity of foam glass before and after modification, as well as the economic feasibility of the work.
