High power transmission using waveguides with parabolic reflectors

摘要

In summary, we propose to realize low-lossand high-power transmission by increasing the surface area ratio A and by introducing parabolicguiding and focusing mechanism. By utilizingnumerical simulation, performances of theproposed mechanism are compared withconventional mechanisms in terms of acousticpressure and power. As a result, the proposedmechanism with double parabolic reflectors canmost effectively achieve plane and powerfulincident ultrasound. The proposed mechanismpossesses enormous potential in large-tissueultrasound imaging, ultrasound therapeutics,ultrasound microscope, etc.
