Sensitivity is a key factor in the performance of a sensor. To achieve maximum guided-mode resonant optical biosensor sensitivity, a comparison of biosensor sensitivity for Transverse Electric (TE) and Transverse Magnetic (TM) modes based on the distribution of electric fields is presented in this article. A label-free guided-mode resonant optical biosensor is designed using the quarter-wave an...

Channel (ridge) waveguides are produced in bulk 4.5 at.% Yb3+:CaF2 crystals by “deep” diamond saw dicing. They possess a rectangular profile with high aspect ratio (a width of 10–50 ?m and depth 200 ?m) good verticality. The r.m.s. surface roughness the diced side walls is only 0.5 nm. waveguide propagation losses as low 0.13 ± 0.05 dB/cm at ~1 (for 40 wide TM-polarization) they slightly increa...

In this paper we extend the standard Ultra Weak Variational Formulation (UWVF) of Maxwell’s equations in an isotropic medium to the case of an anisotropic medium. We verify that the underlying theoretical framework carries over to anisotropic media (however error estimates are not yet available) and completely describe the new scheme. We then consider TM mode scattering, show how this results i...

Wavelength selective filters represent one of the key elements for photonic integrated circuits (PIC) and many of their applications in linear and non-linear optics. In devices optimised for single polarisation operation, cross-polarisation scattering can significantly limit the achievable filter rejection. An on-chip filter consisting of elements to filter both TE and TM polarisations is demon...

【Abstract】 This invention is method of speech recognition that consists of plural overlapped templatematching (TM). In order to economize calculations of TM, the data of low resolution given by Haar discrete wavelet transform (HDWT) is used. Templates of wavelet coefficient (WC) on waveform are used for recognition of phoneme. A sum of WC in a scale (SWC) corresponds to a frequency component on...

The chemical potential of a graphene layer can be locally interrupted by electrostatic gating or chemical doping. When properly designed, electrically small local interruption can possess quasistatic resonance and be strongly excited by electromagnetic field. This excitation generates a mixed-type semilocalized plasmon wave, e.g., it launches TM mode within the interruption domain and TE modes ...

In this paper we present some uniqueness results on inverse wave scattering by unbounded obstacles for the two-dimensional Helmholtz equation. We prove that an impenetrable one-dimensional rough surface can be uniquely determined by the values of the scattered field taken on a line segment above the surface that correspond to the incident waves generated by a countable number of point sources. ...

The new formulation of the coupled-wave analysis recently proposed by Lalanne and Morris [J. Opt. Soc. Am. A 13, 779 (1996)] and by Granet and Guizal [J. Opt. Soc. Am. A 13, 1019 (1996)] that drastically improves the convergence performance of the method for lamellar gratings and for TM polarization is shown to be badly conditioned for gratings with a small thickness. Numerical evidence obtaine...

This study aimed to evaluate the attitude of pediatricians toward the use of complementary and Traditional Medicine (TM) on children in Muscat, Oman. A cross-sectional survey was performed using a self-completed questionnaire during the year 2012. A total of 67 pediatricians, comprising of 30 males (44.8%) and 37 females (55.2%) participated in the study. The majority of the studied group (83.5...
