In 2007 cloaking with metamaterials is reviewed and deficiencies are presented. At the same time, theoretical solutions are presented that could improve the capability to cloak objects. Later in 2007, a mathematical improvement in the cylindrical shielding to produce an electromagnetic "wormhole", is analyzed in three dimensions. Electromagnetic wormholes, as an optical device (not gravitational) are derived from cloaking theories has potential applications for advancing some current technology.
