Cross Conversion between Surface Plasmon Polaritons and Quasicylindrical Waves
,-0001,():
The optical properties of textured metallic surfaces are governed by the scattering of surface plasmon polaritons (SPPs) and of quasicylindrical waves (CWs), which are both excited by the nano-objects located on the surface. We study here a fundamental scattering process of these fields, namely, the cross conversion of a CW into a SPP. We first show that this inelastic process is inevitable in multi-nanoobject ensembles and then propose a procedure enabling a rigorous calculation of the cross conversion scattering coefficients. Additionally, by mapping this intricate process to a much simpler one, we derive general and simple expressions for the cross conversion efficiency. All predictions are carefully supported by fully vectorial computational results.
