FDTD simulation of Maxwell-Schrodinger system

FDTD simulation of the Maxwell-Schrodinger system in MATLAB

If this MATLAB script is useful to you, please consider citing the following reference in your work:

You can also refer to my MS thesis.

This MATLAB script was written in 2014 by C. J. Ryu. It has the following novel FDTD simulation features implemented based on the vector-potential formulation of Maxwell's equations.

• Perfectly matched layers
• Plane-wave excitation
• Coupled Maxwell-Schrodinger system

The main script to run is MAX_SCHROv4_3.m.

Compatibility issues

This script may not run on your verison of MATLAB since MathWorks has updated MATLAB over the years. The following are fixes that you can apply.

• insertHOGM_MS.m uses hermite which is now called hermiteH which requires the Symbolic Math Toolbox. A great alternative is this MathWorks File Exchange submission.

• updateMaxv2.m uses heaviside which also requires the Symbolic Math Toolbox. You can simply implement this function using an if statement.

    function out = heaviside(n)
    
    if n < 0
        out = 0;
    elseif n == 0
        out = 0.5;
    else
        out = 1;
    end
    
    end
