ABSTRACT:
A solid state acoustic travelling wave lens comprises a thin core layer of acoustic and light transmissive material, such as crystalline quartz, compression-bonded between a pair of outer or cladding layers, such as fused silica, having an acoustic velocity that is only slightly higher than (e.g., less than five percent of) that of the core material. The acoustic mode field characteristic of the weakly guiding device contains no spatial variations caused by Fresnel diffraction in an unguided wave device. In a second embodiment, shear stress coupling between the core and cladding layers is inhibited by interposing very thin liquid boundary layers between the core layer and the cladding layers. Such thin liquid boundary layers, which are relatively more compressible than the core and cladding material, allow longitudinal waves to be transmitted across the core/cladding boundary (through the liquid), but prevent transmission of shear waves therebetween.
