Matching Conditions of Absorption Films for the Capture and Absorb of Microwave Signals

Based on the fundamental theory of EM waves,the matching conditions of absorption material films for complete capture and absorb of microwave signals are studied in detail.In this paper,the theoretical formulas for the analysis of numerical values of the matching conditions are derived strictly.Some applications are also discussed.Based on the fromulas,microwave absorption material films will be designed and provided.
