Coherent matrix of plasmonic beams

Abstract

We consider monochromatic electromagnetic beams of surface plasmon-polaritons created at interfaces between dielectric media and metals. We theoretically study non-coherent superpositions of elementary surface waves and discuss their spectral degree of polarization, Stokes parameters, and the form of the spectral coherence matrix. We compare the polarization properties of the surface plasmons-polaritons as three-dimensional and two-dimensional fields concluding that the latter is superior.
