A high-order numerical method for the nonlinear Helmholtz equation in multidimensional layered media
Journal of Computational Physics, 228(10), 3789–3815.
author keywords: Nonlinear optics; Kerr nonlinearity; Inhomogeneous medium; Material discontinuities; Discontinuous coefficients; Layered medium; Nonparaxiality; Forward scattering; Backscattering; (Narrow) solitons; Paraxial approximation; Nonlinear Schrodinger equation; Arrest of collapse; Finite-difference approximation; Compact scheme; High-order method; Artificial boundary conditions (ABCs); Two-way ABCs; Traveling waves; Complex valued solutions; Frechet differentiability; Newton's method
TL;DR:
The first ever evidence that the singularity of the solution indeed disappears in the scalar NLH model that includes the nonparaxial effects is provided, which enables simulation of the wavelength-width spatialsolitons, as well as of the counter-propagating solitons.

Experimental Validation of the Active Noise Control Methodology Based on Difference Potentials
AIAA Journal, 47(4), 874–884.
TL;DR:
It has been demonstrated that while preserving the wanted sound, the developed approach can cancel out the unwanted noise and the volumetric noise cancellation offered by the proposed methodology along with leaving theWant sound unchanged is a unique feature compared to other techniques available in the literature.
