Why the reflection coefficient attends a zero minimum (around kd=2.15) for a non-porous breakwater ( ε = 0), whereas for a porous breakwater (ε≠0)?

Details:  The reflection coefficient of a submerged single porous breakwater  has been calculated, using a Meshless method in conjunction with the  linear potential wave theory. Why the reflection...
