title: Superluminal tunneling of an electromagnetic X wave through a planar slab
abstract: A study is provided of an X wave undergoing frustrated total internal reflection on the upper surface of a planar slab separating two dielectric media. It is shown that the peak of the field transferred through the slab appears to be transmitted at an ultrafast speed. A general analytic solution is derived and is supported by specific numerical examples that indicate that the transport speed of the peak of the X wave can be much larger than the speed of light.
