Have you always wanted to know what happens when electromagnetic theory needs to be extended to a general relativistic setting but never found the time to dive into the literature about it? Fear not! This issue of IEEE Antennas and Propagation Magazine has just the article for you. It features a nice review of the formulation of electromagnetism in curved space–time, surveying the key concepts and then deriving two equations for characterizing light’s redshift. The authors specifically address the applied electromagnetic community, with notation choices that most of our readers will recognize. If you are not familiar with the general relativity formulations of electromagnetism, do not miss this opportunity to learn more about them.
