摘要:

Near‐field acoustical holography (NAH) is used in the present work to measure the reflection coefficient of porous layers from normal to grazing incidence and for inhomogeneous waves. Measurements are compared with predictions obtained from a recent model. A lateral propagating mode inside the porous layer is evident.
