Natural magnetic materials can control light in unprecedented ways

Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as ...

A Multifunctional FSS with dual band shielding in transmission mode and absorption in reflection mode

Abstract: Here we report a miniaturized frequency selective surface (FSS) which can be used for electromagnetic shielding in the transmission mode in two frequency bands, namely 4.2-5.8 and 8.6-10 GHz ...
