Abstract :
This paper experimentally shows that it is possible for the newly developed hybrid magnetic material (blending the flake powder of the magnetic materials inside the polymer) to suppress the cavity resonance by putting the hybrid magnetic material sheet on the wall inside the cavity. The paper proposes the methodology for obtaining the cavity resonance suppression from the relationship between Q and the ratio of cavity volume to the hybrid magnetic material volume by applying the perturbation method for calculating the Q
