The patent claims to make the EM wave travel faster than *A* speed of light, *not* the speed of light in a vaccuum, which is what relativity is based on. From reading the abstract, I think the "device" simply generates a "heat tunnel", contained by opposing magnetic fields, which therefore means that the air (or other medium)in the tunnel is less dense, meaning EM waves can travel faster than the speed of light *in the surrounding medium*.
