Invariance property in scattering media and absorption

TL;DR

This paper investigates how the invariance property of mean path length influences absorption in diffusive media, revealing that scattering can either enhance or hinder absorption depending on geometry and illumination conditions.

Contribution

It demonstrates that the invariance property regulates but does not prevent absorption maximization, highlighting the complex role of scattering in diffusive media.

Findings

Scattering can increase absorption under certain conditions.

The geometry and illumination significantly affect scattering's impact on absorption.

Invariance property influences but does not restrict absorption optimization.

Abstract

In this paper we deal with the influence on absorption of the diffusive media characteristics framing the problem in connection with the invariance property (IP) of the mean path length. We show that the IP is an important issue that regulates but not prevent the search of absorption maximization by scattering characteristics. We find that the scattering may increase the absorption or even be detrimental, depending on the geometry of the medium and the conditions of its illumination.
