Causality and theories of multiple scattering in random media

Research output: Contribution to journalArticlepeer-review


It is shown that the causal or noncausal behavior of theories of multiple scattering of waves in random media is merely a consequence of the representation of the single scattering process. One can expect causality, and possibly therefore Kramers- Kronig relations, to be satisfied by a theory which either (a) correctly and fully represents the scattering operator of an individual scatterer or (b) though using an on-mass-shell representation such as the Waterman T matrix, excludes scatterer overlap.
