We investigate the general relativistic phase of an electromagnetic wave as it propagates in gravitational field Earth, which is modeled isolated, weakly aspherical gravitating body. introduce coordinate systems to describe light propagation Earth's vicinity along with relevant transformations, and discuss transformations between proper times. represent using Cartesian symmetric trace-free (STF...

The differential theory of diffraction of light by an arbitrary object described in spherical coordinates is developed. Expanding the fields on the basis of vector spherical harmonics, we reduce the Maxwell equations to an infinite first-order differential set. In view of the truncation required for numerical integration, correct factorization rules are derived to express the components of D in...
