Memristive Physical Reservoir Computing

Advanced Science, EarlyView.
Memristors’ nonlinear dynamics and input‐dependent memory effects make them ideal candidates for high‐performance physical reservoir computing (RC). Based on their conductance modulation, memristors can be classified as electronic or optoelectronic types.

Metasurface‐Enabled Active‐Like Passive Radar

Advanced Science, EarlyView.
A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

Avalanche noise in submicrometre pin diodes

Electronics Letters, 1997
It is shown that recent measurements of noise suppression in thin GaAs pin diodes by Hu et al. (1996) can be explained as a dead space phenomenon and are consistent with the /spl alpha///spl beta/ ratio approaching unity at high electric fields.
