Thanks!

fdtd code from shangping guo

nope..but i do agree with you. his work explains the basics of both PWE and FDTD extremely well.
i feel it is a good idea to read his plane wave expansion chapter, before you start simulating using software like MPB.

Thank you VERY MUCH for this!
I've been banging my head against the table trying to write a code like this for past week (I am a PhD student). I really appreciate you posting this.

Dear friends
I am phd student. I try to understand the pwm code in page 8 in the manual.
could any one explain:

for x=1:NumberofPW,
for y=x:NumberofPW,
b=r(x)-r+(2*n+1)+1;
eps2(x,y)=eps20(b);
eps2(y,x)=eps2(x,y);
end
end

regards
