Multi-channel near-field terahertz communications using reprogrammable graphene-based digital metasurface

Digital metasurfaces have opened unprecedented ways to accomplish novel electromagnetic devices thanks to their simple manipulation of electromagnetic waves. However, the metasurfaces leveraging phase-only or amplitude-only modulation restricted the full-functionality control of the devices. Herein,...

However, the metasurfaces leveraging phase-only or amplitude-only modulation restricted the full-functionality control of the devices.

Moreover, we introduce a novel method to directly transmit digital information over multiple channels via the reprogrammable digital metasurface.
