23 April 2008 Efficiency of local surface plasmon polariton excitation on ridges
Author Affiliations +
We investigate experimentally and numerically the efficiency of surface plasmon polariton excitation by a focused laser beam using gold ridges. The dependence of the efficiency on geometrical parameters of ridges and wavelength dependence are examined. The experimental measurements accomplished using leakage radiation microscopy. The numerical simulations are based on Green's tensor approach.
