Abstract：The absorption characteristics of the mixed-cavity structure anechoic coating with air backings is studied based on the finite element method. The absorption characteristics of anechoic coating with mixed-cavity structure were studied. The calculation result indicates that the absorption characteristics of this kind of cavity structure are superior to single-cavity structure under the same perforated percentage. Then, the absorption properties of anechoic coating with mixed-cavity structure at full-frequency range were further improved by optimization design. The influence of coating structure parameters on absorption characteristics is studied.
