摘要: It is shown that by measurement of the complex Fresnel reflection coefficients a thick slab ferrite for both parallel and perpendicular polarization, permittivity permeability can be found. In case are too small to measured accurately, it also arbitrary but known thickness, backed metal plate, may used. The necessary formulas given cases. They simple explicit do not involve solution transcendental equations, as might have been expected in second method proposed.
