This technique is applied to study the combined refraction and diffraction of plane monochromatic waves by a circular cylindrical island mounted on a paraboloidal shoal. By using the direct solution for the wave dispersion equation by Hunt [J. Waterw., Port, Coast., Ocean Div. Proc ASCE 4 (...
We present a surface-wave inversion method that inverts for the S-wave velocity from the Rayleigh wave dispersion curve using a difference approximation to the gradient of the misfit function. We call this wave equation inversion of skeletonized surface waves because the skeletonized dispersion curve...

We present analytic solution to fundamental in wave multiple scattering theory Lippmann-Schwinger (LS) integral equation for electric field quantum mechanical type tensor T- scattering operator by nonmagnetic arbitrary shaped particle with given scalar dielectric permittivity and specific conductivity in free...
Solid curves show the results obtained from numerical solution of Eq. (8). Inset: Spatial profiles of the condensate density calculated for different magnitudes of the coefficient g describing the nonlinear magnon–magnon interaction with all other parameters fixed. The curve labeled g = gFIT ...
This allows repeatable measurements to be achieved with little dispersion among samples and long-term stability against the fading effect (less than 1% fading after 30 days) [9,13]. Therefore, RPL glass dosimeters have been widely used as one of the accumulation-type dosimeters, among other ...
The phenomenon was simulated using the Wave Optics module of COMSOL Multiphysics 6.0. The model geometry was the following: the upper layer of air, with thickness of 2 µm; the lower layer of GaSe, with thickness of 3 µm; the modification surface, given as the 4th order polynomial of...
where, in general, ω = ω(k) with the explicit form for the dispersion determined from the structure of the equation and in the case of a nonlinear equation, even the amplitude of the solution (height of the wave) is a function of k and, therefore, of ω. In the case of the KdV...
A dispersion relation for sound wave propagation in the porous medium is derived from the propagation equations and a model solution is sought based on plane-wave decomposition using orthogonal cylindrical functions. The explicit analytical solution equation of the scattered field show that it is also...
of excitation power fraction (I1/I10). All the data could be well described by a power law of the form IPL ~ Iαwith an α equal to 1.07, 1.72 and 2.02 for the QDs, WL, and GaAs band-edge emission, respectively. Below, we adopt a simple three-level rate equation model to ...
