Long-range surface plasmon polaritons on asymmetric double-electrode structures

Yang Hyun Joo, Myoung Jin Jung, Jaewoong Yoon, Seok Ho Song, Hyong Sik Won et al.
An asymmetric double-electrode structure composed of metal strips separated by a dielectric core layer, all on a metal slab, is proposed as a long-range surface plasmon-polariton (LR-SPP) waveguide. LR-SPP modes on asymmetric structures, including straight, S-bended, and Y-branched strips, are found ... [Appl. Phys. Lett. 92, 161103 (2008)] published Mon Apr 21, 2008.
