| dc.description | We study analytically and numerically field/intensity correlations in wave transport through volume-disordered waveguide. The obtained channel and spacial correlations deviate from those found in framework of Dorokhov-Mello-Pereyra-Kumar (DMPK) formalism, that we relate to inapplicability of equivalent channel approximation in DMPK. We show that this can be remedied by introducing boundary correction -- an escape function which depends on the waveguide geometry -- that describes wave transport near a boundary between random medium and free space. We obtain the expressions for field/intensity channel and spacial correlation functions which agree with the numerics and are consistent with the perturbative expressions in slab geometry as well as experiments conducted in Q1D. | |
