File Information
Description

A simple one-dimensional finite-difference time-domain (FDTD) electromagnetic routine that allows the user to specify arbitrary permittivity, permeability and conductivity profiles. Useful for helping students to visualize reflection, transmission, wave velocity and impedance concepts. Will also show WKB approximation.

MATLAB release MATLAB 5.3 (R11)

Great code, thanks. Reference H. Loui's well-documented 1D FDTD Yee implementation; you can get it by searching "1d fdtd yee" ... it's the first hit as of today.

A very nice and straightforward example. Some references would be a nice addition for the students.

It´s a very good FDTD introductory example.
