Analytical Solution of Diffraction by a Composite Cylinders Above a Special Bottom Undulation in Uniform Water

We consider the co-axial cylindrical structure as a composite submerged solid cylinder above special bottom undulation, i.e., circular plate at impermeable horizontal bottom. diffraction problem of proposed in water finite depth. This can be expressed wave energy converter. The variables separation and eigenfunction expansion methods are utilized to determine analytical solutions for their identified sub-domains. By using orthogonality Bessel functions expression diffracted velocity potentials. achieve system linear equations after suitably truncated obtain infinite series. work may helpful designer design appropriate device so that one extract maximum energy. created used many applications conventional
