Enhanced THz Transmission by Bull’s Eye Structure Integrated with a Concentric Gold Hemisphere

In this work, a hemispheric gold particle is introduced to the conventional bull’s eye structure that enhances extraordinary optical transmission in the terahertz region. Transmission enhancement is a result of the coupling of surface plasmon polaritons generated by periodic grooves and localized su...
