Information transfer through disordered media by diffuse waves | | S.E. Skipetrov
; | | Date: |
18 Oct 2002 | | Journal: | Phys. Rev. E 67, 036621 (2003) | | Subject: | Disordered Systems and Neural Networks; Mesoscopic Systems and Quantum Hall Effect; Optics | cond-mat.dis-nn cond-mat.mes-hall physics.optics | | 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 $ propto n$ and obtain explicit analytic expressions for $/n$ in the limit of $n o infty$ and $k ell o infty$, where $k= 2pi/ lambda$, $lambda$ 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. | | Source: | arXiv, cond-mat/0210415 | | Services: | Forum | Review | PDF | Favorites | |
