I'm a beginner in FDTD programing.
Anyone have a MATLAB code to solve the irregular grid problem??

There is a book on FDTD with some 2-D code included. I don't remember the title now. Check your library.

Simple fdtd program is very easy write, especially you are using matlab.
Once the formulation are derived, writing the code is just a matter of time. You may first start by writing a simple 1D code with both side PEC, then adding ABC. This step will verify and solidify your concept. After 1D, then 2D and 3D. You may try implementing PML in 2D, after it is verified then extend to 3D.

Extending regular grid to irregular grid is just a piece of cake, but you may take care of the stability condition.

For updating fields in your simulation domain, try avoid using "for loop". "For loop" is incredible slow in matlab.

I upload an FDTD code in matlab in one dimension. It is very easy to understand it and than to extend it in 2 and 3 dimensions.
