Problems solved by technology

[0002] When a plane wave encounters a solid structure, it will always reflect, causing the wave field around the solid structure to be disordered, and the characteristics of the plane wave will no longer be maintained.
In previous theoretical research and practice, there has been no effective way to reduce the reflection of waves while maintaining the wave field characteristics of plane waves

Abstract

The invention discloses a non-reflection wave regulation and control device and a design method. The device has the same height of an area structure within the inner diameter ri, the height of the device at the outer diameter ro is 0, the height of the area structure between the inner diameter ri and the outer diameter ro is gradually changed, and a plurality of baffles are arranged in the heightgradually-changed area to form grooves. When the cone-frustum-shaped body is immersed in water and plane waves with specific wavelengths and frequencies are incident, the plane waves are hardly reflected on the periphery of the cone-frustum-shaped body, so that the wave energy loss on the periphery of the cone-frustum-shaped body is reduced, the waves entering the cone-frustum-shaped body are still the plane waves, and meanwhile, the wave amplitude is amplified.

Description

Technical field [0001] The invention belongs to the field of wave theory and engineering, and particularly relates to a non-reflective wave control device and a design method. Background technique [0002] When a plane wave encounters a solid structure, it will always be reflected, causing the wave field around the solid structure to be disordered and no longer maintain the characteristics of a plane wave. In the previous theoretical research and practice, there has been no effective way to reduce the reflection of waves while maintaining the wave field characteristics of plane waves. If a structure can be proposed that can significantly eliminate the wave reflection around the solid structure, or even without reflection, it can greatly reduce the wave energy loss around the solid structure, which is very valuable for improving the wave energy collection efficiency. In addition, this structure can be used for the measurement of wave field parameters, which can obtain the charact...
