Rigorous coupled-wave analysis of electromagnetic scattering from lamellar grating with defects

structures have continuous spectra in the wavenumber space, and the main problem of the spectral-domain approach is connected to the discretization scheme on the wavenumber the discretization scheme in the Brillou...

Complex wavenumber Fourier analysis of the B-spline based finite element method

We present the results of one-dimensional complex wavenumber Fourier analysis of the B-spline variant of Finite Element Method (FEM). Generally, numerical results of elastic wave propagation in solids obtained by FEM are polluted by...

Two methods for determination of the effective wavenumber of Gaussian beams in absolute gravimeters

This paper presents two methods for evaluation of the effective wavenumber of a so called diffraction correction in absolute gravimeters. The first method and transmitted to a photodetector. However, precision of this m...

Multispectral atomic force microscopy-infrared nano-imaging of malaria infected red blood cells

at the nanoscale. AFM-IR maps are acquired using a single wavenumber value: they show either the absorbance plotted against a single wavenumber value or a ratio of two absorbance values. This was achieved by converting the disc...

Undamping Force in a Nonlinear Hydrodynamical Cochlear Model

Mammalian cochlea is an active system, this phenomenon can be demonstrated by the undamping feedback force, which is caused by the outer hair cells located on the basilar membrane (BM). This study shows that the undamping force could be obtained from...
