Abstract: An analytical study is presented for oblique wave scattering by a floating elastic plate in a body of water over a porous seabed. The problem is solved using the eigenfunction expansion method under the assumption of small-amplitude surface waves and structural response. The study aims to look into the interaction between oblique waves and a floating elastic plate that serves as an effective breakwater. Numerical results for the plate having free edge, simply-supported edge and clamped edge are compared and most of the results are analysed for plate having clamped edge. Numerical results for the reflection and transmission coefficients are computed and examined for various values of the wave, porous bed and structural parameters
