Interactive Finite Difference Time Domain Toolbox

2-dimensional FDTD-Toolbox (Yee Grid,Matrix based,current like sources,PML boundaries, GUI based)

Description

The interactive FDTD-toolbox for MATLAB is a simulation software to model and
simulate two dimensional optical systems in TE-polarization.
It was designed for educational purposes - no further knowledge of MATLAB or computational physics is required. The software is embedded in a graphical user interface in which all
the simulation parameters can be set. Furthermore, geometrical structures are defined via draggable forms which makes the program very intuitive and easy to use. Even difficult simulation structures can be set up in a few minutes.
The program works very efficient, accurate and reliable. To achieve this, a matrix-based algorithm according to Yee’s FDTD-method was implemented allowing easy
parallelization. Furthermore, perfectly matched layer (PML) boundary conditions and current like sources are included for realistic scenarios.

I'd really love to see you give the user more freedom and maybe implement:
=====================================

1. if one could load an map that was created outside the drawing tool.

2. option for complex refractive index instead of just epsilon. N and k are simply more common plus you now only offer real permittivity, as far as I can see

This is a very nice toolbox that makes it quite easy to demonstrate basic optic phenomena to students! Also the direct video output is very nice.

Anyways, Soeren should add in the description that the toolbox tutorials and info's are found in the "Educational Tools" section of the website, i.e. at http://www.problemsinelectrodynamics.com/tools

Thumbs up!
