Abstract
The disturbance of the transmission of a diffusive medium due to an ob ject hidden in it can be expressed in terms of an effective charge and dipole moment. In the mesoscopic regime, beyond the diffusion approxi mation, we calculate this effective charge acid dipole moment. Various objects are considered: a single point scatterer, a localised density of such scatterers and a small sphere. (C) 1998 Elsevier Science B.V. All rights reserved.
