Zain rifqi@ukm.edu.my Lamb waves Phononic crystal slabs Phononic waveguiding Link to publisher's homepage at http://ijneam.unimap.edu.my We demonstrated theoretically the wave guiding of elastics waves in a two-dimensional (2D) phononic crystal (PnC) slab. The simulation model based on the Finite Element Method (FEM) was used to calculate the dispersion relation of unit cells that shows a complete band gap between frequency, f=312–412 kHz. The supercell technique to simulate two waveguides size shows filtering frequencies between 365-397 kHz within the band gap. We discuss the frequency shift of the wave guide as a function of the defect size for the possibility of elastic wave filtering application. ` 2021-02-25T01:00:26Z 2021-02-25T01:00:26Z 2020-12 Article International Journal of Nanoelectronics and Materials, vol.13(Special Issue), 2020, pages 83-90 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/69848 en NANOSYM, 2019; Universiti Malaysia Perlis (UniMAP) |
