Near-field interactions and nonuniversality in speckle patterns produced by a point source in a disordered medium
Near-field interactions and nonuniversality in speckle patterns produced by a point source in a disordered medium
A point source in a disordered scattering medium generates a speckle pattern with non-universal features, giving rise to the so-called C_0 correlation. We analyze theoretically the relationship between the C_0 correlation and the statistical fluctuations of the local density of states, based on simple arguments of energy conservation. This derivation …
