Reply To: hybrid plasmonic waveguide based biosensor

Could you please elaborate more regarding to the results you want? what source you are using? it seems like a plane wave but the structure seems not periodic. This can only be an approximation. Usually plan wave should match with periodic boundary conditions. Please consider it carefully.

We have examples for your reference:

You can certainly simulate the sensitivity.
