摘要
Various embodiments relate to refractive index-distributed acoustic quantum crystals, which have a specified size, are arranged in a matrix form having a layer arrangement in the Y-axis direction and a column arrangement in the X-axis direction on a two-dimensional plate, and a unit having a hole in the center In the refractive index distribution acoustic quantum crystal including a cell, the size of the perforation of the unit cell may be set so that the refractive index distribution acoustic quantum crystal can act as a refractive index distribution lens with respect to a bending wave having a specified frequency. . Various other embodiments are possible.
