We show that engineered photonic metamaterials composed of alternating layers of suitable dielectrics and metals can support different kinds of surface waves (SWs) under robust and readily achievable experimental conditions. The supported SWs include Dyakonov SWs, hybrid plasmons, and Dyakonov plasmons. In particular, in contrast to conventional physical settings, we show that the high form birefringence exhibited by the metamaterials allows Dyakonov SWs, or dyakonons, to exist within large angular existence domains and levels of localization similar to plasmons, thus making dyakonons available for practical applications.
我们展示了由适当的电介质和金属交替层组成的工程光子超材料可以在稳健且易于实现的实验条件下支持不同类型的表面波(SWs)。所支持的 SW 包括 Dyakonov SW、混合等离子体和 Dyakonov 等离子体。特别是,与传统物理环境相比,我们表明超材料表现出的高形式双折射允许 Dyakonov SW 或 dyakonons 在类似于等离子体的大角度存在域和局域化水平内存在,从而使 dyakonons 可用于实际应用。
