Invisibility Cloak Research Moves Forward at Michigan Tech

Michigan Technological University’s invisibility cloak researchers have done it again. They’ve moved the bar on one of the holy grails of physics: making objects invisible.

Just last month, Elena Semouchkina, an associate professor of electrical and computer engineering at Michigan Tech, and her graduate student, Xiaohui Wang, reported successful experimental demonstration of the use of non-conductive ceramic metamaterials to cloak cylindrical objects from microwave-length electromagnetic waves.  Previously, Semouchkina had designed a non-conductive glass metamaterial cloak that worked  with infrared frequency waves, which are shorter than microwaves.
