Greetings
I have a rectangle plasmonic waveguide (Ag on Si with air superstrate) with thickness T and width W. I would like to know what kind of modes can support my waveguide. As I understood, this problem cannot be solved analytically (Pierre Berini, "Plasmon-polariton waves guided by thin lossy metal flms of fnite width: Bound modes of asymmetric structures" DOI: 10.1103/PhysRevB.63.125417) and must be solved numerically.
Thus, I would like to ask how can I build dispersion curves for my waveguide? Thank you
