论文摘要
我们将先前的工作[ARXIV：1908.09095]扩展到具有源的麦克斯韦方程式。我们的工作显示了如何在辐射仪中的Kerr-Newman背景上为Maxwell Field构建弱势矢量潜力。与我们以前的工作一样，向量电位具有从HERTZ的潜在求解Teukolsky's方程中获得的“重建”术语，以及一个“校正”术语，可以通过沿即将爆发的原理无效射线来获得，该术语可通过。在点粒子源的情况下，讨论了我们向量电位的奇异性结构。
We extend previous work [arXiv:1908.09095] to the case of Maxwell's equations with a source. Our work shows how to construct a retarded vector potential for the Maxwell field on the Kerr-Newman background in a radiation gauge. As in our previous work, the vector potential has a "reconstructed" term obtained from a Hertz potential solving Teukolsky's equation with a source, and a "correction" term which is obtainable by a simple integration along outgoing principal null rays. The singularity structure of our vector potential is discussed in the case of a point particle source.
