scatteringdissemination

Scatteringdissemination is a term used in several disciplines to describe the spread of a substance, wave, or information through a medium via scattering events, resulting in a broad and often diffuse distribution. The concept emphasizes how repeated deflections disrupt a direct trajectory and promote widespread reach beyond the initial source.

In physical sciences, scatteringdissemination refers to the multiple scattering of waves in turbid or heterogeneous media. The process is governed by parameters such as the scattering coefficient μs, absorption coefficient μa, phase function p(θ), and anisotropy g. From these, the mean free path ℓs and the transport mean free path ℓtr are defined to quantify how far a particle or photon travels before its direction is randomized. Under strong scattering, emergent behavior can be described by the radiative transfer equation or, in the diffusion regime, by a diffusion equation that predicts temporal broadening and spatial spreading of energy.

In information and social contexts, the term is used metaphorically to describe how messages disseminate through networks via successive interactions. Here, individuals or nodes act as scattering centers, altering, delaying, or amplifying content as it propagates. Modeling approaches include diffusion on networks, branching processes, and percolation theory.

Applications include imaging in turbid media (such as diffuse optical tomography), atmospheric science, acoustics, and the study of information diffusion in social systems. The term is not widely standardized; often the physics and information perspectives are described using related, more specific concepts such as diffusion, radiative transfer, or diffusion of innovations.
