Frozen Differential Scattering in Reconfigurable Complex Media

open access: yesLaser &Photonics Reviews, EarlyView.
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Economics of Public WiFi [PDF]

open access: yesAustralian Journal of Telecommunications and the Digital Economy, 2014
Local governments in urban regions continue to find the idea of public or municipal WiFi attractive. This is for multiple reasons, not all of which are based on economic logic (such as city branding, vote-buying, emergency services, commercial lobbying, peak-traffic broadband off-loading).
