Modelling and calculation of reflection and transmission characteristics from water foam specimens in kind of layered structure

Abstract

Model of water foam was presented as same layers with different dielectric and structural characteristics. Data of experimental research of dielectric properties ε and tg δ of the water foam specimens was used for calculations in wide microwave band of 8 - 12 GHz. The reflection and transmission characteristics of electromagnetic waves from foam structures with foaming ratio of layers in range from 6 till 350 were calculated. The results show an opportunity to use water foam structures in conditions of electromagnetic influences as absorbers which are able to protect working personnel from dangerous influence of electromagnetic waves.
