Oblique wave action on perforated caisson breakwater with inner horizontal porous plate

Based on linear potential theory and matched eigenfunction expansion method,this study develops an analytical solution for oblique wave interaction with a perforated caisson breakwater with an inner horizontal porous plate,which is confirmed by comparing with a multi-domain boundary element method solution.Numerical examples are given to examine the effects of the incident wave angle and the relative wave chamber width on the reflection coefficient and wave forces.The research results may serve as reference for physical model tests and practical engineering.
