Spatiotemporally modulated metasurfaces can control electromagnetic waves, but such systems are typically limited to free-space-only and waveguide-only platforms. Here we report a 1-bit space鈥搕ime-coding metasurface antenna that can extract and mould guided waves into any desired free-space waves ...
Researchers at Southeast University, University of Sannio and Université Paris-Saclay-CNRS showed that a specific PM, known as a space-and-time-coding metasurface, could simultaneously support both sensing and wireless communication. Their paper,publishedinNature Communications, introduces two promising sc...

Spatiotemporally modulated metasurfaces can control electromagnetic waves, but such systems are typically limited to free-space-only and waveguide-only platforms. Here we report a 1-bit space–time-coding metasurface antenna that can extract and mould guided waves into any desired free-space waves ...
