| Abstract: | In this paper, the absorbing mechanism for one layer microwave absorber was introduced firstly. An optimizing method of frequency tracking for electromagnetic parameters of microwave absorber was proposed. Amplitude frequency characteristic of the material was obtained under optimal fitting together by using the optimizing method. By analyzing influence of the dispersion of electric magnetic parameters on the performance of the absorber, the conclusion was obtained that ultimate approach for optimizing microwave absorber is considering electric magnetic parameters,frequency and the thickness of the absorber matching simultaneously. |
