On the Role of Caustic in Solar Gravitational Lens Imaging

arXiv:1712.02038 · doi:10.1093/ptep/pty119

Abstract

We consider scattering of electromagnetic waves from a distant point source by the gravitational field of the sun, taking the field oblateness due to the quadrupole moment of the sun into account. Effects of the field oblateness can play an important role in the high resolution solar gravitational lens imaging in the sub-micrometer wavelength range of the electromagnetic spectrum.
