Abstract:
Two ferrite materals, Ferramic E and Ferramic E 1960, were used as magnetc layer absorbers. The measured reflection coefficients were below 10 in the frequency anges 4.2 x 10 to the 7th to 3.8 x 10 to the 8th and 2.4 x 10 to the 8th to 7.6 x 10 to the 8th, respectively. The thicknesses of layer were 0.88 cm and 0.5 cm respectively. These measurements confirmed the reflection coefficients calculated from the relaive dielectric constant and relative permeability. Various materials were tested with respect to their applicability as absorber material. Author
