Abstract
When considering optimized design of panel with composite layer including porous material, we have to know the detail mechanism. In this paper, we studied radiaiton power from flat panel with composite layer by creating simple model using trasfer matrix method and wavefield transformation. We validated proposed model by comparing with FEM results. From an example of comparison between fiber type porous material and foam type, we clarified the different behavior of those materials, which is different vibration shape appeared at compsite layer surface due to lateral direction wave number dependent. The result shows some of possibility like leading different results of panel shape optimization in the case of with/without composite layer.
