Physics of Invisibility

A team led by scientists at Duke University's Pratt School of Engineering has demonstrated the first working "invisibility cloak." The cloak deflects microwave beams so they flow around a "hidden" object inside with little distortion, making it appear almost as if nothing were there at all.

Interesting stuff . But ,in my view even , it scientist achieve invisibility there are ways of defeating it . For example . The polarized light partial invisibility comes unstuck when a light of different polarity hits the scene . For normal light invisibility a normal radar frequency scan would defeat it in my opinion . Years ago , during the NATO war of aggression against Serbia , this country downed a US Stealth bomber . Serbia was given the right radar frequency to scan. I know that " stealth " is not invisibility , but here I am talking about the concept .
