摘要： A structure for bending transversal elastic waves around a zone to isolate of a plate, has an anisotropic Young's modulus and/or a heterogeneous mass density. The wavelengths of the elastic waves to bend are large with respect to the thickness of the plate and small with respect to the other dimensions of the plate. The structure is made by defining a meshing of a peripheral zone surrounding the zone to isolate; dividing the peripheral zone into several elementary rings and several elementary angular sectors; and forming, in each mesh delimited by an elementary angular sector and an elementary ring, a structural element in a material having a Young's modulus and/or a mass density different than those of the material forming the plate, the dimensions of the meshes and of the structural elements in the plane of the plate being less than half the wavelengths of the elastic waves to bend.

摘要： An acoustical phase plug for use in loudspeakers produces a planar rectangular wavefront, or a wavefront with a desired amount of curvature, from the output aperture of the phase plug device when presented with a planar circular wavefront at the input aperture. The phase plug utilizes a waveguide that equalizes the travel paths from the input aperture to the output aperture. The waveguide essentially eliminates surface discontinuities thereby resulting in the reduction of diffraction of the wavefront travelling through the phase plug device.
