The excitation conditions for surface plasmon polaritons (SPPs) on a silver-gold bilayer coated sinusoidal grating can be varied over a wide range by tuning the azimuthal grating orientation (α). Grating coupling induces rotation of the SPP wave vector which, for specific conditions, can be directed...
