Retrieving the Green’s Function from Cross Correlation in a Bianisotropic Medium
Development of theory and experiments to retrieve Green’s functions from cross correlations of recorded wave fields between two receivers has grown rapidly in the last seven years. The theory includes situations with flow, mechanical and electromagnetic disturbances and their mutual coupling. Here an electromagnetic theory is presented for Green’s function retrieval from cross correlations that...
متن کاملRetrieving the elastodynamic Green's function of an arbitrary inhomogeneous medium by cross correlation.
A correlation-type reciprocity theorem is used to show that the elastodynamic Green's function of any inhomogeneous medium (random or deterministic) can be retrieved from the cross correlation of two recordings of a wave field at different receiver locations at the free surface. Unlike in other derivations, which apply to diffuse wave fields in random media or irregular finite bodies, no assump...
متن کاملRetrieving the Green’s function in an open system by cross correlation: A comparison of approaches (L)
We compare two approaches for deriving the fact that the Green’s function in an arbitrary inhomogeneous open system can be obtained by cross correlating recordings of the wave field at two positions. One approach is based on physical arguments, exploiting the principle of time-reversal invariance of the acoustic wave equation. The other approach is based on Rayleigh’s reciprocity theorem. Using...

15 صفحه اولBianisotropic negative-index metamaterial embedded in a symmetric medium
In order to more clearly observe the bianisotropic effects due to fabrication-induced structural asymmetries in negative-index metamaterials based on a fishnet structure, it is necessary to measure the optical properties with symmetric substrate and superstrate bounding layers. This is accomplished in this report using an indexmatching fluid and identical substrate and superstrate glass materia...
