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.

Last month, Todd Humphreys, an assistant professor in the Department of Aerospace Engineering and Engineering Mechanics and WNCG, testified before the U.S. House Committee on Homeland Security's Subcommittee on Oversight and Management Efficiency. Humphreys was asked to speak at the hearing, "Unmanned Aerial System Threats: Exploring Security Implications and Mitigation Technologies," because of his expertise in unmanned aerial vehicles, UAVs.
