We consider the waveguiding by thin patterned slabs embedded in a homogeneous medium. In the longwave limit, the wave spectra of slabs are found to be well described by a single frequency-independent parameter, which we call the “guiding power". The guiding power can be evaluated in an effective medium approximation, similar to the Maxwell Garnett theory, but modified for the local field correc...
BACKGROUND There does not exist a comprehensive parameter for guiding selection of short or long segment fusion for degenerative lumbar scoliosis (DLS). The aim of our study was to investigate the applications of the width-to-length ratio in guiding selection of the surgical approaches for DLS. METHODS A retrospective analysis was performed of 142 patients with DLS who underwent operative tre...
Abstract The presence of a thermally annealed metallization layer on top GaAs slab waveguide proofed to be strong impact the optical device behavior. Induced by stress chip elasto-optical effect imprinted variation refractive index that led anti-guiding and guiding effects. In order enable precise prediction behavior we present 3D mechanical simulation which provides detailed insights overall s...
