  "abstract": "We consider the information content h of a scalar multiple-scattered, diffuse wave field $\\psi(\\vec{r})$ and the information capacity C of a communication channel that employs diffuse waves to transfer the information through a disordered medium. Both h and C are shown to be directly related to the mesoscopic correlations between the values of $\\psi(\\vec{r})$ at different positions $\\vec{r}$ in space, arising due to the coherent nature of the wave. For the particular case of a communication channel between two identical linear arrays of $n \\gg 1$ equally-spaced transmitters/receivers (receiver spacing a), we show that the average capacity $<C> \\propto n$ and obtain explicit analytic expressions for $<C>/n$ in the limit of $n \\to \\infty$ and $k \\ell \\to \\infty$, where $k= 2\\pi/ \\lambda$, $\\lambda$ is the wavelength, and $\\ell$ is the mean free path. Modification of the above results in the case of finite but large n and $k \\ell$ is discussed as well.",
