ROCHESTER CLOAK: A research project that uses inexpensive, readily available lenses to cloak objects from view has received a patent. Physics professor John Howell and then graduate student Joseph Choi ’16 (PhD) first demonstrated the array of lenses in 2014 and have since worked to refine it. Known as the “Rochester Cloak,” the system is formally known as the “Paraxial Cloak Design and Device”—at least that’s what the U.S. Patent Office called it when issuing Patent No. 9,557,547.
