Infrared metamaterial design is a rapidly developing field and there are increasing demands for effective optimization and tuning techniques. One approach to tuning is to alter the material properties of the metals making up the resonant metamaterial to purposefully introduce resonance frequency and bandwidth damping. Damping in the infrared portion of the… (More)
Background: Due to recent rapid economic development, China has seen changes in what foods households are purchasing as well as the general health of the population. In the United States and other high‐income countries, in‐home scanner programs allow consumer packaged goods companies to measure household level grocery store food purchases and analyze trends… (More)
We experimentally demonstrate the magnetic mirror behavior of all-dielectric metasurfaces at optical frequencies through phase measurements using time-domain-spectroscopy. The unique boundary conditions of magnetic mirrors can lead to advances in sensors, photodetectors and light sources.
