Perturbational solution for propagation in periodically bent nematic liquid crystals and thin films

Abstract

The Maxwell curl postulates have been analyzed for propagation in the vertical microstructurally signif cant plane of a periodically bent nematic (PBN) medium. The ordinary modes are unaffected by the anisotropy and the periodic inhomogeneity of the PBN medium, but the extraordinary modes are. Simple expressions, applicable for small anisotropy parameters, have been found. ABSTRACT Numerical analysis for computing resonant frequencies of uniaxially anisotropic cylindrical resonators is presented. The resonator is placed on a grounded isotropic substrate and is couered with a metallic tuning plate. The generalized impedance boundary conditions are employed along the axis of the resonator to simplify the boundary-calue problem. Ample numerical results are presented, explicitly showing the dependence of the resonant frequency on the variation in the elements of the permitticity tensor. 0 1996 John Wilqy & Sons, Inc.

Microsprings and microcantilevers: studies of mechanical response

“…The study of their properties and methods of construction has remained a subject of interest, as increasing usage of these components continues. Theoretical examinations of structurally chiral media [1,2] and cantilever principles [3] are available, and provide motivation for work in numerous MEMS domains [4,5]. With the testing of the unique microspring and microcantilever structures produced by the glancing angle deposition (GLAD) technique, the promise for developing future devices utilizing GLAD thin films may be realized, which show potential for resonator and MEMS applications.…”
