Against dogma: On superluminal propagation in classical electromagnetism

© 2014 Elsevier Ltd. It is deeply entrenched dogma that relativity theory prohibits superluminal propagation. It is also experimentally well-established that under some circumstances, classical electromagnetic fields propagate through a dielectric medium with superluminal group velocities and superluminal phase velocities. But it is usually claimed that these superluminal velocities do not violate the relativistic prohibition. Here I analyze electromagnetic fields in a dielectric medium within a framework for understanding superluminal propagation recently developed by Geroch (1996, 2011) and elaborated by Earman (this issue). I will argue that for some parameter values, electromagnetic fields . do propagate superluminally in the Geroch-Earman sense.
