Sorry, I dont clearly understand you. The numerical solutions are very close to the analytical ones.

I'm a green hand. Your code only shows numerical results. It's hard for me to know how to solve it analytically, right. If you can get analytical solutions in one dimension. Can you could teach me something? I'm sorry to bother you

I hope FDTD can solve real problems, but I don't get real solutions in the book. With only some electromagnetic propagation information, I can't tell right from wrong

hi, you may find the reflection and transmission coefficients from a slab in any book of electromagnetics e.g. Balanis' Advanced Engineering Electromagnetics. I used the following code in MATLAB (n and n0 are the impedances in the slab and in the air)
Z1=n0./n; Z2=n./n0;
%the thickness of the slab d=20e-9;
%Reflection coefficient R=((1-Z1).(1+Z2)+(1+Z1).(1-Z2).exp(-2.g.d))./((1+Z1).(1+Z2)+(1-Z1).(1-Z2).exp(-2.g.d)); %Transmission coefficient T=4.exp(1j.b0.d)./((1-Z1).(1-Z2).exp(-g.d)+(1+Z1).(1+Z2).exp(g.*d));
