New electrostatic (or, more accurately, quasi-electrostatic or slow electric) surface waves, i.e., electrostatic Dyakonov-like surface waves, are predicted theoretically. These surface waves are localized at the interface between a metallic nanowire-based hyperbolic metamaterial and an isotropic medium and travel along the interface. Solving a modified Laplace’s equation in conjunction with the appropriate boundary conditions, the dispersion relation, power flow, energy density, group (energy) velocity, and polarization are obtained for these electrostatic Dyakonov-like surface waves, and some numerical solutions are presented.

基于金属纳米线的双曲超材料支撑的静电Dyakonov型表面波

从理论上预测新的静电（或更准确地说，准静电或慢速电）表面波，即类似Dyakonov的静电表面波。这些表面波位于基于金属纳米线的双曲超材料和各向同性介质之间的界面处，并沿界面传播。结合适当的边界条件求解修正的拉普拉斯方程，获得了这些静电Dyakonov类表面波的色散关系，能流，能量密度，基团（能量）速度和极化，并给出了一些数值解。
