Scattering of waves, e.g., light, due to medium inhomogeneity is ubiquitous in physics and considered detrimental for many applications. Wavefront shaping technology a powerful tool defeat scattering focus light through inhomogeneous media, which vital optical imaging, communication, therapy, etc. based on the matrix (SM) extremely useful handling dynamic processes linear regime. However, imple...

In this paper, we numerically simulated a glass-based all-optical 1×N power splitter with eleven different configurations using soliton breakup in a nonlinear medium. It is shown that in addition to reconfigurability of the proposed splitter, its power splitting ratio is tunable up to some extent values too. Nonlinear semivectorial iterative finite difference beam propagation method (IFD-...

double- unsymmetric-plan medium-rise buildings subjected to bi-directional seismic excitation are complex structures where higher-mode effects in plan and elevation are important in estimating the seismic responses using nonlinear static or pushover analysis. considering two horizontal components of the ground motions makes the problem more intricate. this paper presents a method for nonlinear ...

We discuss a time-harmonic inverse scattering problem for nonlinear Helmholtz equation with compactly supported inhomogeneous objects that are described by refractive index in unbounded free space. Assuming the knowledge of far field operator, which maps Herglotz incident waves to patterns corresponding solutions problem, we show refraction is uniquely determined. also generalize two reconstruc...
