Problem
The silver film of the previous problem (λ0=600nm, ϵ~m=−8.88+1.44i, air on the far side) is instead deposited on the base of an SF10 glass prism of refractive index np=1.723, in the Kretschmann geometry. Using the real part of the bare-interface dispersion relation, compute the internal angle of incidence θ inside the prism at which the surface plasmon polariton is resonantly coupled.
