Abstract
A metallic sub-wavelength grating with slits filled with dielectric was proposed to achieve broadband and enhanced Extraordinary Optical Transmission (EOT) for Transverse Electric (TE) wave. The physical mechanism for the improvements of the transmission spectrum was also revealed. It was found that the Fabry–Perot cavity resonance in the grating slits was the cause of the enhancement of the EOT and the waveguide modes theory was the fundamental mechanism for the broadened bandwidth of the transmission.
