Finite Difference Method

Python Stencil Environment also know as PySE is a new python library for solving Partial Differential Equations with the Finite Difference Method (FDM). This is still a quite new library, and the current release must be considered as beta software. It is quite rough around the edges,... Platforms: *nix

A simple partial differential equation (PDE) with boundary conditions is examined:d/dx( x dy/dx ) = xy(0) = y(1) = 0.Integrate the PDE twice to get its solution. Then apply the boundary conditions and get a contradiction. The boundary value problem(BVP)has no solution.Regardless, apply the finite... Platforms: Matlab

FDTD(Finite Difference Time Domain) is the most easiest method of EM Solver.In this code i just demonstrate that how can we launch multiple sources in a single time,and how they can combine effect with in single time domain. The Sources are taken as 20GHz Sine wave and number of signal are... Platforms: Matlab

FDTD is Finite Difference Time Domain method,but due to truncated it it will cause the reflectional on its boundary that will cause unnecessary noise to our simulation domain. So minimizing this unwanted signal we use PML(Perfectly Matched Layer)which can absorb this unwanted signal and so there... Platforms: Matlab
