The formula of power reflectivity following the generalized matching laws of multi-layer absorbing coatings is deduced by using the theory of transmission line at the oblique incidence of electromagnetic wave. Through the application of the three dimensional grid methods,the absorbing performance research for the single-layer absorbing material is analyzed. The analysis results show that,within the bandwidth from 1 to 18 GHz,θ_1 65°,μ_(r1) 1,ε_(r1)35,and 1 M_1 6,the value of reflectivity can meet the requirements for the absorbing performance of materials in the current fields of military and civilian. At the same time,the theoretical analysis and the grid method in this paper will play a directional guidance role for the actual material designs and applications.
