Engage the cloaking device

It's called a "plasmonic cover" by its proponents, Andrea Alù and Nader Engheta of the University of Pennsylvania, and it works by resonating in tune with the light that would normally illuminate an object, thereby reducing the amount of light that is scattered, making the object in question more difficult to see. Eliminate all the scattering, and the object is effectively invisible.

There is, of course, a downside: the cover must be tuned for any specific wavelength of light, which means anything you can see in ordinary visible light, which is made up of a multitude of wavelengths, isn't shieldable. Yet.
