This paper demonstrates how the evaluation of the electromagnetic scattering from 3D rough multilayers can be analytically conducted in the framework of the Volumetric Perturbative Reciprocal Theory (VPRT). The advantage of the proposed approach is twofold. Indeed, in this framework the pertinent closed-form (first-order) scattering solution is derived in a conceptually clean way and is directly interpreted in terms of the Rumsey's reaction concept. Accordingly, the concept of multireaction is introduced and discussed. Finally, it is important to note that methodologically the VPRT opens the way to the unified treatment of both interfacial and volumetric scattering in random media.

Abstract
This paper demonstrates how the evaluation of the electromagnetic scattering from 3D rough multilayers can be analytically conducted in the framework of the Volumetric Perturbative Reciprocal Theory (VPRT). The advantage of the proposed approach is twofold. Indeed, in this framework the pertinent closed-form (first-order) scattering solution is derived in a conceptually clean way and is directly interpreted in terms of the Rumsey's reaction concept. Accordingly, the concept of multireaction is introduced and discussed. Finally, it is important to note that methodologically the VPRT opens the way to the unified treatment of both interfacial and volumetric scattering in random media.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
