Multilayered structures were designed on both sides of a thin silver film to let both transverse-magnetic- and transverse-electric-polarized electromagnetic waves propagate along a thin metal film simultaneously in the same configuration, as so-called long-range surface-plasmon-polariton (LRSPP) waves. Based on the admittance analysis and design, the propagation length of an unpolarized LRSPP wave can be extended by more than 1 order of magnitude compared with previous results.
