Invisibility Exposed: Physical Bounds on Passive Cloaking

July 5, 2016
Prof. Andrea Alù’s and PhD candidate Francesco Monticone’s research paper titled ‘Invisibility Exposed: Physical Bounds on Passive Cloaking’ will be published in the Optical Society’s flagship journal Optica in the upcoming issue. Together, Prof. Alù and Monticone have established quantitative physical limitations on the performance of cloaking devices, a technology that allows objects to become invisible or undetectable for electromagnetic waves, such as radio waves, microwaves, infrared and visible light.
