Investigation of reflection and transmission characteristics in the foam medium

Abstract

The model of water foam as a multilayer dielectric is presented in the paper. The structure was composed of seven layers, each of them had its own value of dielectric permittivity and loss tangent. The layers had a thickness of 5 and 10 mm for comparison. Calculations were made for the electromagnetic wave range of 8 - 12 GHz. Layers had value of foaming ratio of very wide range of 6 - 350. The results proved that model under discussion had data of good quality for absorbers design.
