Abstract (in Japanese) (See Japanese page) 
(in English) By using transparent solid silicone (PDMS) as a structural medium, design and propagation analysis of a phononic structure with high spatial design freedom and capable of wavefront visualization was performed. By visualization experiments based on the Fresnel method, we confirmed the wavefront of the mode-controlled propagation wave in the acoustic waveguide. And we designed the acoustic wave waveguide using the defect mode in the phononic crystal. We also designed a GRIN acoustic wave lens using multilayered phononic crystals with refractive index distribution (GRIN).
