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 ...

Two-dimensional (2D) space-encoded metamaterials enable the progressive development of a multitude of functionalities for controlling electromagnetic (EM) waves. Recently, time-modulated phase-coded ...

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 ...
