Summary

We derived a formula for wave field coherence in dissipative media. For small dissipation and isotropic sources, coherence relates to the Green's function in 2D and 3D, but not 1D.

  • Investigation of wave fields in homogeneous dissipative media with stationary sources.

    • Main Results:

    • A closed-form analytical expression for the spectral degree of coherence was derived.
    • In low-dissipation and isotropic source conditions, coherence is proportional to the imaginary part of the Green's function.
    • This universal form of coherence was demonstrated for 2D and 3D fields, but not 1D.

    Conclusions:

    • The study reveals a universal relationship between wave field coherence and the Green's function under specific conditions.
    • The findings are applicable to scalar wave fields in 2D and 3D dissipative media.
    • The dimensionality of the field plays a critical role in the nature of spatial coherence.
