Building virtual magnetic monopoles and EM wormholes

Really interesting idea here from Alan Greenleaf (University of Rochester) et al. The idea is to manipulate electrical permittivity and magnetic permeability to create objects that act like invisible tunnels. The object would not be detectable to EM observations from the side but seen head on, one would see light passing through. The object would be constructed from meta-materials.
