Problems solved by technology

The existing technology attempts to develop a series of submerged dikes to achieve coastal protection according to the characteristics of Bragg resonance that reflects waves toward the sea. However, the superposition of incident and reflected waves caused by Bragg resonance itself also plays a role in focusing wave energy, that is, improving the wave energy in a certain area. energy density, this phenomenon has not yet attracted enough attention from the perspective of wave energy utilization
