[Meep-discuss] poynting vector

Dear Steven and others, In Meep, how can we output the magnitude of the poynting vector? I only know the x,y,z components of it. And every time when I use the order " output-tot-pwr", there is a warning"too many field components" at all time, even though my structure is very small. I don't

[Meep-discuss] band structure

Dear Steven and others, I want to calculate the SW(surface waves) band structure of a dispersive slab.I can get the rigorous result by TMM.But the result calculated by Meep is not consistent with the theoretical result. I don't know why.Attachment is the ctl file. Thanks in advance! Best wishes

[Meep-discuss] dispersive material

Dear Steven and others, When I calculate the dispersive material, why the output of the structure are all black? In this case, are there any ways to see the field patterns of the dispersive material?Thanks in advance! Best Regards, Huang___ meep-dis
