We propose a new method for integrating metasurfaces in optical design using semi-analytical modeling of dielectric nanostructures. The latter computes the output phase an electric field incident on metasurface, allowing their use with ray-tracing software. This tool provides to systems while built-in optimization processes avoid time-consuming computation. To demonstrate applicability and vers...

This article discusses a semi-analytical method for solving modelling equations blood flow through compliant vessels. He's method, also called the variational iteration (VIM), is used to find an approach solution in explicit form. The chosen problem has been handled by asymptotic reduction of associated incompressible Navier–Stokes equations, obtain one-dimensional nonlocal model with source te...
