Dispersion relation of double metal-strip waveguides

  • 발행 : 2006.07.01

초록

An idea for extension of propagation range of surface plasmon-polaritons(SPP), which are guided on metal-strip waveguides, is suggested. Slight modification in refractive indices and/or separation gaps can increase two orders of magnitude in propagation distance of SPPs. Dispersion relations of extended long-range SPP modes excited on vertically coupled SPP waveguides are discussed in detail.
