Investigating Far-Field Spectra and Near-Field Features of Extraordinary Optical Transmission Through Periodic U- to H-Shaped Apertures

Investigating Far-Field Spectra and Near-Field Features of Extraordinary Optical Transmission Through Periodic U- to H-Shaped Apertures

By exploiting the in-house finite-difference time-domain (FDTD) program, the optical properties of a designated 2-D array of U- to H-shaped holes perforated on a metallic film are analyzed. Some specific near-field features are found to be associated with the three mechanisms underlying the transmis...
