Foam absorbing material properties in range of 8-12 GHz
Keywords:reflection, transmission, absorbing materials, foams, scalar reflectometer, multyfrequency measurements, time-domain analysis
AbstractThe experimental results of measurements of electromagnetic wave reflection and absorption for some specimens of water foam in free space for the frequency band 8-12 GHz are presented. The specimen thicknesses were in the range 2-110 mm; the range of foaming ratio was 28-55. It has been shown that the reflective and absorption characteristics of the foam absorbing materials depend on the foaming ratio, specimen thickness and time of foam existence.
