Inspired by the recent optical investigations on the hyperbolic metasurfaces, we study the possibility of new quasi-electrostatic waves propagation in such anisotropic 2D materials that do not propagate in the case of a regular 2D medium. The analytical result shows that the dispersion relation of these waves is free from the effects of permittivities of the surrounding media. These new waves may be considered as longitudinal quasi-electrostatic waves.

双曲超表面的纵向准静电波

受最近对双曲线超曲面的光学研究的启发，我们研究了在这种各向异性的2D材料中传播新的准静电波的可能性，而在常规2D介质中，这些材料不会传播。分析结果表明，这些波的色散关系不受周围介质介电常数的影响。这些新波可以被认为是纵向准静电波。
