The altering permittivity tensor of a hyperbolic medium from diagonal to off-diagonal by the constructive manipulation of the optical axis (also called tilted hyperbolic medium) has attracted much interest recently. Here, the electromagnetic field solutions of waves interacting with a tilted hyperbolic medium are established. Detailed calculations reveal that when a transverse magnetic (TM) polarized wave is incident from a tilted hyperbolic medium to a dielectric medium, tangential components of electric fields are expected to be discontinuous at the interface. Extraordinary surface voltages are induced at the inner boundary of the tilted hyperbolic medium, which prevents the reflection of electromagnetic waves. This alternative behavior of induced extraordinary surface voltages enriches the understanding of continuity across the boundary and provides a novel perspective for their realizations among multiple experimental platforms.
通过对光轴进行构造性操作(也称为倾斜双曲介质),使双曲介质的介电常数张量从对角形式变为非对角形式,这一现象近来引起了广泛关注。在此,我们建立了与倾斜双曲介质相互作用的波的电磁场解。详细计算表明,当横向磁(TM)极化波从倾斜双曲介质入射到电介质时,电场的切向分量在界面处预计会出现不连续。在倾斜双曲介质的内边界会感应出异常表面电压,这阻止了电磁波的反射。感应异常表面电压的这种不同寻常的行为丰富了我们对边界连续性的理解,并为在多个实验平台上实现它们提供了一个新的视角。
