Space‐Time Metasurface Antenna Enabled High‐Dimensional Electromagnetic Modulation for Intrinsic Physical Layer Security

open access: yesAdvanced Science, EarlyView.
The concept of high‐dimensional EM modulation using the STMA for physical layer secure communication is illustrated in figure. The STMA consists of a series of programmable unit cells, with 1‐bit reconfigurable phase states (0/π). The STMA is excited by a monochromatic continuous wave (CW) at frequency fc and controlled by a field‐programmable gate ...

The pinning method: From pinning to data preparation

open access: yesDendrochronologia, 2007
The pinning method is one of the various approaches to trace the intra-annual cambium dynamics of trees along a highly resolved time axis. After a brief retrospect on preceding developmental steps, the pinning of trees and the measurement of the radial ...
