A single nanometric aperture surrounded by a circular channel groove in a metallic screen can increase the electric field intensity inside the central aperture up to 50 fold. Detailed analysis of cavity modes and their coupling through surface plasmon wave determine the parameters leading to maximum field enhancement. This effect can be used in high-efficiency single-molecule fluorescence analysis in attoliter volumes.
