Title

PROPAGATION OF ACOUSTIC WAVES IN A PHOTONIC CRYSTAL PLATE WAVEGUIDES

Authors

Abstract

We have studied propagation of acoustic waves in a photonic crystal plate and related waveguides. A two dimensional photonic crystal plate consisting of circular steel cylinders which form a square lattice in an epoxy matrix was studied. The Bloch theorem was employed to deal with the periodic condition. The dispersion curves and displacement fields were calculated to identify the band gaps and eigen modes. Our results shows that eigen modes of acoustic wave inside the wave guides and the modes are affected by the geometry arrangement of wave guides. Inside the photonic crystal plate waveguides, wave propagation is well confined within the structure. We have analyzed the bulk acoustic waves in the unbounded photonic crystals with a free surface. We found that many applications of photonic crystals were designed accordingly, such as elastic wave filters, couplers and wave guides. We also found that as a result of the waveguiding, the photonic plate with a polyline defect that forms a sharply bent waveguide and it was applied to use for frequency selection of Lamb waves. The obtained results were compared with previously obtained results of theoretical and experimental works and were found in good agreement.
