New 'active' invisibility cloak design 'drastically reduces' visibility

A great headline from The Independent today. I don't know if it's a case of intentionally or unintentionally funny. Regardless, here's what it refers to:

A new type of “active” invisibility cloak that could operate over a broad range of frequencies has been developed by researchers at the University of Texas in Austin.
By employing a “superconducting thin film” that is electrically powered the cloak could overcome the limitations of current “passive” designs.
Scientists have previously created small-scale invisibility cloaks that work only in response to very limited types of light. The researchers at the University of Texas give the example of an object that is made invisible to red light, but becomes bright blue as a result, “increasing its overall visibility”.
"Our active cloak is a completely new concept and design, aimed at beating the limits of [current cloaks] and we show that it indeed does," Professor Andrea Alù, a lead author on the study, told the BBC.
"If you want to make an object transparent at all angles and over broad bandwidths, this is a good solution […] We are looking into realising this technology at the moment, but we are still at the early stages."

A great photo, too.
