Spatial control of surface plasmon polariton excitation at planar metal surface
Surface plasmons Thin films Phase modulation Spatial light modulators
2015/8/6
We illustrate that the surface plasmon polariton (SPP) excitation through the prism coupling method is fundamentally limited by destructive interference of spatial light components. We propose that th...
