匀速运动各向同性手征媒质中的正负相速传播

Negative- and positive-phase-velocity propagation in an isotropic chiral medium moving at constant velocity

Tom G. Mackay, Akhlesh Lakhtakia

摘要:

分析电磁平面波在同向运动参考系中的时空均匀、时间非局域、各向同性、手征性介质中的传播表明,相对于所有非同向运动惯性参考系,该介质在空间和时间上都是非局域的。利用电场和磁场的洛伦兹变换,我们证明了在同向运动参考系中具有正相速度的平面波在某些非同向运动参考系中可能具有负相速度。类似地,在同向运动框架中具有负相速度的平面波在某些非同向运动框架中可以具有正相速度。

英文摘要:

Analysis of electromagnetic planewave propagation in a medium which is a spatiotemporally homogeneous, temporally nonlocal, isotropic, chiral medium in a co-moving frame of reference shows that the medium is both spatially and temporally nonlocal with respect to all non-co-moving inertial frames of reference. Using the Lorentz transformations of electric and magnetic fields, we show that plane waves which have positive phase velocity in the co-moving frame of reference can have negative phase velocity in certain non-co-moving frames of reference. Similarly, plane waves which have negative phase velocity in the co-moving frame can have positive phase velocity in certain non-co-moving frames.
