Abstract

We consider a regular and bounded dielectric body moving at a speed V|V|, following a constant vector field VV, with respect to a reference frame. In this frame, the special relativity implies that the Maxwell system is derived through the constitutive equations linking the moving speed V|V| and the speed of light cc in the background medium (as the vacuum for instance). Based on this model, we derive the well-poseness of the related forward scattering problem in the natural regime where VcCte\frac{|V|}{c}\leq C_{te} with an appropriate constant Cte<1C_{te} <1 that we estimate. In particular, we show the invertibility of the related Lippmann-Schwinger system in this regime and state the corresponding Born series in terms of the ratio Vc\frac{|V|}{c}. As an application, we state and show the unique identifiability of the inverse problem of detecting the dielectric body, without knowing the moving speed V|V| or VV, by illuminating it with incident electromagnetic waves propagating at the speed cc. Such identifiability result makes sense in the regime under consideration.
