2014 Recent experiments have shown that interdigital transducers can couple strongly to plate modes in piezoelectric composite membranes. In this paper the dispersive properties and the piezoelectric coupling (039403BD/03BD) to these plate modes are presented The various types of modes are identified and related to crystalline symmetry. Results are given for stiffened-shear modes in zinc oxide ...
We propose a practical realization of electromagnetic spherical cloaking by layered structure of homogeneous isotropic materials. By mimicking the classic anisotropic cloak by many alternating thin layers of isotropic dielectrics, the permittivity and permeability in each isotropic layer can be properly determined by effective medium theory in order to achieve invisibility. The model greatly fa...
We studied the first-order diffractedmoiré fringes of transparent multilayered structures comprised of irregularly deformed periodic patterns. By a comparison study of the diffractedmoiré fringe pattern and detailed microscopy of the structure, we show that the diffractedmoiré fringe can be used as a nondestructive tool to analyze the alignment of multilayered structures. We demonstrate the ali...
