Transparent Topological Meta‐Diplexer via Tightly Confined Valley Surface States

Advanced Science, EarlyView.
An optically transparent topological metasurface supporting tightly confined valley surface states enables robust and flexible wave routing in an ultrathin platform. A compact transparent meta‐diplexer with spatially and spectrally separated channels is realized, while communication experiments verify high‐fidelity signal transmission, opening new ...

The timescape of smart cities [PDF]

Annals of the American Association of Geographers, 2017
To date, critical examinations of smart cities have largely ignored their temporality. In this paper I consider smart cities from a temporal perspective arguing that they produce a new timescape and constitute space-time machines. The first half of the paper examines temporal relations and rhythms, exploring how smart cities are the products of and ...
