Abstract: In this paper, localization phenomena of inplane timeharmonic elastic waves propagating in layered phononic crystals (PNCs) with different fractal superlattices are studied. For this purpose, oblique wave propagation in ...

Abstract: In this paper, acoustic wave propagation in a twoor threedimensional phononic crystal consisting of Helmholtz resonators embedded in a fluid matrix is studied. The band structures are calculated to discuss the influence ...

Abstract: Twodimensional (2D) equations of piezoelectric bimorph nanoactuators are presented which take account of the surface effect. The surface effect of the bimorph structure is treated as a surface layer with zero thickness. ...

Abstract: In the present paper, the DirichlettoNeumann map method is employed to compute the band structures of twodimensional phononic crystals with smoothly sliding connection conditions between the matrix and the scatterers, which ...
