Complex Mechanism of Enhanced Optical Transmission Through a Composite Coaxial/Circular Aperture

Making use of the FDTD simulation, we study light transmission properties of a composite coaxial/circular aperture milled in a thin metallic film. Representing the aperture as consisting of segments of coaxial and hollow waveguides, connected in series, we show that there are three characteristic fr...
