Space-time coding techniques exploit multiple transmit and receive antennas to enhance the reliability and capacity of wireless links by encoding data across spatial and temporal dimensions. Emerging ...
The systematic framework for the proposed multi-liquid identification is depicted in Fig. 1. The system comprises a space-time-coding metasurface illuminated by a feeding pyramidal horn antenna, a ...
Programmable metasurfaces (PMs), also sometimes referred to as reconfigurable intelligence surfaces, are smart surfaces that reflect wireless signals, but can also dynamically manipulate ...
What if our biggest idea about reality is built on a hidden misunderstanding? A new philosophical look at space-time ...
