For the study of parametric excitation, we have considered that the origin of Stimulated Brillouin Scattering (SBS) nonlinear interaction lies in the third-order optical susceptibility in a centrosymmetric, doped semiconductor which is subjected to transverse magnetic field. The third-order optical polarization in a SBS system arises due to nonlinear current density and acousto-optical strain o...

Efficient numerical methods are required for the design of optimised devices. In magnonics, primary computational tool is micromagnetic simulations, which solve Landau-Lifshitz equation discretised in time and space. However, their cost high, complexity output hinders insight into physics simulated system, especially case multimode propagating wave-based We propose a finite-element modal method...

Existence of backward TE volume modes which are to be identified as Magnetostatic Wave (MSW) in anisotropic single-negative slab with partly negative permeability tensor component have already been revealed by present authors. In this paper, detailed modal analysis has been carried out for this kind of TE volume modes to find out their novel and peculiar properties. From these numerical results...

This paper examines the generation and propagation of a Third order solitary water wave along the channel. First the Incompressible Smoothed Particle Hydrodynamics (ISPH) numerical method is described and the boundary condition handling method is presented. The numerical model is then used to simulate solitary wave propagation along the fixed depth channel. The numerical results are compared wi...

i.e., that the free currents flow in closed loops. Likewise, the time derivative of the fourth Maxwell equation implies that Jfree has no time dependence in magnetostatics. Often, magnetostatics is taken to be the situation in which ∇ · Jfree = 0 and D, E and Jfree have no time dependence, without explicit assumption that B and H also have no time dependence. Discuss the possibility of waves of...
