Investigation of Wave Focusing over a Parabolic Step

  • Conference paper
Hydrodynamics of Ocean Wave-Energy Utilization

Abstract

We report here upon an exploratory investigation of wave focusing over a bottom step which has a parabolic shape in the horizontal plane. Although building of a large-scale reflector can be a very costly project, the idea of using a parabolic reflector--either in the form of a wall or a step discontinuity at the bottom-- will be presented along with small-scale experimental results to test the feasibility of such systems. Some theoretical considerations for analytical description will be discussed.
