摘要：

In this study, we consider the propagation of hard electromagnetic emissions in the magnetosphere of a pulsar based on General Relativity and nonlinear vacuum electrodynamics. We show that the radiation will propagate at different velocities in the magnetosphere of a pulsar and form two normal modes, which are polarized in mutually orthogonal planes. We calculate the delay between the two orthogonal modes as they propagate from the pulsar to the detection device. (C) 2015 Elsevier B.V. All rights reserved.
