Sub‐THz Multifunctional Metasurfaces for Independent Transmission or Reflection Phase Manipulation

Advanced Optical Materials, EarlyView.
This article presents a rigorous analysis, design, and characterization of a novel sub‐THz metalens and reflective metasurface. Unlike bulky optical systems, the proposed thin, planar metasurface enables dual‐band full‐space wavefront control, via low‐loss transmission and reflection phase tuning, offering compact integration and improved ...

BT Technology Journal, 2000
The next three years will see the introduction of packet data offerings on GSM. There will also be the emergence of new radio coding schemes to bring data rates up to 50 kbit/s. The introduction of 3rd Generation networks bringing the capability to deliver 500 kbit/s to the wide area will also be seen.
