This paper deal with the design of thin dielectric and ferromagnetic which consist of double layered structure, the first layer being covered with either loss less or lossy ferromagnetic material, there by making re lay impedance of the absorber match that of the free space with fairly thickness. The design procedures for two type of absorber are introduced, one being for the case where loss-less ferromagnetic material is applied over the surface of the first layer dielectric, when it has larger Tan δ_G than the optimum value and the other being for the absorber, which use thin lossy ferromagnetic material for the surface of the first layer dielectric, which has smaller Tan δ_G than optimum values.
