University of Toronto has come up with a design that can shield an object entirely from radar. additionally you can make objects appear larger or smaller as well. Basically they took a pile of mini antennae and put it as a shell around an object. Generate a frequency and block yourself from radar. Article goes on to say that future designs could be used to make an object disappear from sight as well.
All very interesting stuff.

Researchers from the University of Toronto have successfully demonstrated an "invisibility cloak" that can make objects undetectable to radar.
Prof. George Eleftheriades and PhD candidate Michael Selvanayagam have designed a new way to cloak an object by surrounding it with small antennas that radiate an electromagnetic field, effectively making it "disappear" from microwave and radio wave detectors.
