Hi, Nizamov Shawkat,
For your first question, Benjamin has noted that your simulation sizes
are too small. When you cut the region into
several chunks in MPI, each chunk should be large enough that its
surface points are much less t

Originally, FDTD method cannot set two field components into one real

I am also focusing on the Q-factor calculation recently. And I give

The complex EM fields may not be necessary in dielectric material or

Hi,Ryan
In a waveguide, each mode determined by its cross-section field
distribution can propagate forwardly and backwardly which can be

Then if one guided

Reading the part of your codes, i think you misunderstand the meanings
of after-time and at-every. (after-time 50 $step-function) means the

the first part of "eq?" returns values at T when T>50 and the second one

If you are familiar with Emacs， its Scheme-mode may help you debug the
