Loss calculations


What are the appropriate condition to get the leakge losses of leaky waveguide (rectangular, fiber), plasmonic structure. The basics things shown in Knowledge base is not fitting to our designed structure.


If you are trying to find leaky modes, chances are you will need to use PML boundary conditions. Also, some convergence testing will be needed to estimate the loss of the modes. If you can tell me more about your simulation, or upload the file here, I might be able to make more comments. We have some tips in the KB for finding leaky modes, if you have not seen it.
