文摘A single metallic nanoslit is employed for investigating the contribution of Surface Plasmon Polaritons(SPPs) to Extraordinary Optical Transmission(EOT) based on rigorous electromagnetic theory and the Spectrum Analysis Method(SAM). Numerical results shows that the SPP is the main factor responsible for the EOT, and a phase singularity is observed.
