| Outline of Final Research Achievements |
Periodic structure called “Phononic Crystal”, which enables tailoring of elastic wave propagation, has been designed for new energy-transport/harvesting devices and for new THz wave generation/control.
Specifically, we have performed i) numerical design and proof-of-principle experiments of GRIN lenses consisting of a 2-dimensional phononic structure, ii) molecular-dynamics analysis of THz wave propagation on a piezoelectric thin film and its control by a periodic hole array, and iii) numerical design of an acoustic diode based on a piezoelectric-dielectric periodic structure.
