Analyze 3D FEM Model to Apply 2D Phononic Crystals in Transducers

Interdigital transducers (IDTs), as one-dimensional (1D) phononic crystals (PnCs), have been used for many years to excite and receive surface acoustic waves (SAWs) in applications of resonators, filters and sensors. In recent years, two-dime...
