Title:  Cloaking by Change of Variables


Abstract:
We say a region of space is "cloaked" with respect to electromagnetic 
measurements if its contents -- and even the existence of the cloak -- are 
inaccessible to such measurements. One recent proposal for achieving cloaking 
takes advantage of the coordinate-invariance of Maxwell's equations. I shall 
explain this scheme, including its mathematical basis and its apparent limitations.
