Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

open access: yesAdvanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

Breaking the waves

Science, 2015
When Hurricane Irene hit North Carolina's coast in 2011, waves 2 meters high began pounding the shore. Two properties on Pine Knoll Shores, a community on one of the state's many barrier islands, provided a study in contrasts. One homeowner had installed a concrete bulkhead to protect his yard from the sea.
