Dear Meep developers and users,
I faced the following problem recently. I would appreciate it if someone could help. First I wonder, when we plot " epsilon.h5 " file for MIM structure for instance, in which metal is defined as either Drude metal, or Lorentz_drude metal, what PNG shows in metallic part is just the term "epsilon_infinity" of the dielectric function of metal. That is metallic parts are plotted as a dielectric with epsilon=epsilon_infinity. Second, as you may know when we use "run-k-points", an epsilon.h5 file is automatically outputted to ensure whether our structure is defined correctly or not. However, I have realized that the epsilon.h5 file that is outputted with "run-k-points" is different of the epsilon profile that we output with the following command: (run-until 50 (at-beginning output-epsilon)) I have attached the completely different PNG views for epsilon.h5 file generated both by run-k-point and the above command. The file starting with "2" belongs to the epsilon.h5 generated by "run-k-points". I have also read this file in MATLAB, but there is no smooth step function for dielectric. I have included this file as well. I would appreciate any help or comment. Many thanks, Roya
