Condition for invariant spectral degree of coherence of an electromagnetic plane wave on scattering

Fourth-order correlation statistics of an electromagnetic plane wave scattered by a quasi-homogeneous medium

“…Very recently, Wang and Zhao deduced the condition that, for the case that a completely coherent scalar plane wave incident on a random medium, the corresponding spectral degree of coherence of the scattered field may remain invariant in the entire scattering process [22]. Subsequently, Li et al extended the condition into the three-dimensional electromagnetic case [23], which had shown some differences compared with the previous one. The problem of cloaking of a slab object in scalar wave theory has also been solved within the first-order Born approximation [24].…”

Polarization-induced coherence changes and conditions for the invariance of the spectral degree of coherence produced by an electromagnetic wave scattering on a collection of particles

“…Correlationinduced and polarization-induced coherence changes of an electromagnetic wave on scattering were outlined Contents lists available at ScienceDirect journal homepage: www.elsevier.com/locate/jqsrt in [9,10]. Furthermore, the conditions for the invariance of the spectral degree of coherence of a coherent scalar plane wave while it is scattered from random media were obtained in [11], and then the conditions for the scalar wave were extended to a more general three-dimensional electromagnetic wave case in [12]. On the other hand, the beamlike condition for a plane wave was obtained while it is scattered on a stochastic medium [13].…”
