GRADIENT-INDEX PHONONIC-CRYSTAL LENS AND METHOD FOR DESIGNING THE SAME

摘要

Various embodiments relate to a refractive index distribution type acoustic quantum crystal plane lens. In a refractive index distribution type acoustic quantum crystal plane lens that controls the behavior of an acoustic wave having a specified frequency, a unit cell in which a scattering body of the same size is formed at a center is horizontal. A layer consisting of an aggregate arranged in a direction includes at least one super cell stacked in a vertical direction according to a target refractive index distribution, and the at least one super cell is provided between the layer and each neighboring layer, and the It may include a dividing unit forcing the traveling direction of the acoustic wave traveling in the refractive index distribution type acoustic quantum crystal plane lens to face the horizontal direction. Other various embodiments are possible.
