Perturbation of the directivity function in inhomogeneous anisotropic media

Ivan Psencik

Summary

Perturbation formulae for the directivity functions of the point force source and moment tensor point source in arbitrary anisotropic media are given. By specifying the background medium isotropic, directivity functions for arbitrary weakly anisotropic structures are obtained.
