What I want here is to write a code and get the result in the Figure 12(a,b). The work is to reproduce the figure a and b in [url removed, login to view] from the attached paper.
This project is about Dyadic Green's function, scattering losses of waveguide. You may need some knowledge of optics, electromagnetic field. You can plot the figure by Python or Mathematics or Matlab.
If you have any question, please let me know!
