A photonic surface wave, a propagating optical mode localized at the interface of two media, can play significant role in controlling flow light nanoscale. Among various types such waves, waves with hyperbolic dispersion or simply supported on anisotropic metal interfaces be exploited to effectively control propagation lightwaves. We used semi-analytical and numerical methods study nature several configurations three-layers metal–dielectric–metal systems including isotropic cases where cladding layers were assumed have infinite thickness. approaches phenomena. showed that wave tuned from diverging converging plane by combination metals different properties.
