Effective Electro-Magnetic Parameters for Microwave Absorbing Ceramics

摘要

Microwave diffraction behavior of microwave absorbing ceramics was investigated by numerical calculation, and effective electro-magnetic parameters of the ceramics was obtained by comparing the diffraction behavior with that of homogeneous material. Then, the calculated results were compared with the results of effective medium models, aiming to investigate the applicability of these models. The obvious difference between these results were pointed out, and the possible reason for this difference is also discussed.
