摘要：

In this paper, a method is proposed to compact waveguide devices at a desired frequency. In this method, a previously designed hollow waveguide is filled with several dielectric and ferrite layers alternately so that the characteristic impedance of the waveguide is not changed. First, the permittivity and permeability of a fictitiously mixed material is obtained. Then, the required permittivity and permeability of dielectric and ferrite layers are obtained at desired frequency. The usefulness of the proposed method is verified using some theoretical and simulation examples.
