thank you. Please from where have you obtained this relation for conductivity: Material(4,3) = lineH/(Z0*lineW*dy); ?

Question

In the program, is the dielectric layer thickness 0.4 mm?

but in the original problem, it is 1.588 mm

can you please provide the corresponding conference paper for equations as reference?

nageswara rao, you can increase PML layers with PML parameter. Ex - is a physical x-component of electric field, Gx and Fx - additional variables of UPML technique for FDTD, k_Ex_a and etc. - transformation coefficients of FDTD method

nageswara rao

how can we select the number of PMLs?
what these parameters Ex,Gx,Fx,Hx,Bx, k_Ex_a,b,c,d are stands for?
