摘要:

我们报道了一种新型的Dyakonov表面波的预测,沿两个负各向异性介质之间的界面的平坦带传播。结果表明,由于两金属板之间的条形波导的特定边界,负各向异性介质满足表面波条件。在弱各向异性近似下,用微扰理论研究了这种模式。负单轴晶体中Dyakonov表面波的存在促使我们重新考虑适合其实际应用的材料清单。我们相信,这项工作开辟了一个新的未开发的研究领域的表面波。

英文摘要:

We report the prediction of a new type of Dyakonov surface waves that propagate along the flat strip of the interface between two dielectrics with negative anisotropy. It is shown that the surface waves condition is satisfied for negatively anisotropic dielectrics due to specific boundaries of the strip waveguide confined between two metallic plates. Such modes are studied by the perturbation theory in the approximation of weak anisotropy. The existence of Dyakonov surface waves in negative uniaxial crystals motivates us to reconsider the list of materials suitable for their practical implementation. We believe that this work opens a new unexplored research area in the field of surface waves.
