Abstract

The transmission properties of a plasmonic multilayer structure with a defect, which can be a nanoslit, were investigated. The transmission spectrum through the slit embedded in the plasmonic multilayer structure presents a Fano-like shape at a transmission peak of 580nm. The enhanced transmission is due to the localized surface plasmon resonant within the cavity of the plasmonic multilayer. The increased transmission factor has a maximum of 5.5 and it also performs loose angle tolerances of 10 and 20° for 1 and 3 dB losses, respectively.
