Concealment by uniform motion

Counterposition and negative refraction due to uniform motion

Refraction of obliquely incident plane waves due to the interface of a vacuous half-space and a half-space occupied by a simply moving, nondissipative, isotropic dielectric-magnetic medium is considered, when the medium's velocity lies parallel to the interface and in the plane of incidence. Counterposition of the refracted wavevector and time-averaged Poynting vector occurs when the medium's velocity is sufficiently large in magnitude and makes an obtuse angle with the incident wavevector. The counterposition induced by relative motion occurs whether the refraction is negative or positive whe…

Fresnel reflection coefficients in the Fourier domain for a planar surface in uniform motion parallel to its interface

本文利用经典电动力学和狭义相对论，在傅里叶域中严格计算了平行于界面匀速运动的介质平面的反射系数，发现运动引起交叉极化、表面等离激元单向性和非互易性。

Surface-plasmon-polariton waves guided by the uniformly moving planar interface of a metal film and dielectric slab

We explored the effects of relative motion on the excitation of surface-plasmon-polariton (SPP) waves guided by the planar interface of a metal film and a dielectric slab, both materials being isotropic and homogeneous. Electromagnetic phasors in moving and non-moving reference frames were related directly using the corresponding Lorentz transformations. Our numerical studies revealed that, in the case of a uniformly moving dielectric slab, the angle of incidence for SPP-wave excitation is highly sensitive to (i) the ratio $β$ of the speed of motion to speed of light in free space and (ii) the…
