Abstract :
We present high-performance terahertz intensity modulators based on a new class of reconfigurable meta-surfaces that offer extreme diamagnetic switching capability over a broad frequency band. We experimentally demonstrate record high modulation depths (> 70%) and modulation bandwidths (> 1.5 THz) through a fully integrated platform at room temperature.
