Proposed manipulation of spin currents in GaAs crystal using the Pockels effect

AIP Advances, 2017
A spin current could induce linear electro-optical electric susceptibility, thus the incident light could interact with the spin current via Pockels effect.

Polarized foregrounds power spectra vs CMB

, 2002
We briefly review our work about the polarized foreground contamination of the Cosmic Microwave Background maps. We start by summarizing the main properties of the polarized cosmological signal, resulting in “electric” (E) and “magnetic” (B) components ...

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Optimal E-Field Vector Combination for a Highly Focused Antenna-Array [PDF]

, 2014
A near-field highly focused circular phased-array antenna for 5.8-GHz radio frequency identification (RFID) applications is presented. The electric field (E-field) at the focus is enhanced by a constructive vector combination in a three-dimensional (3-D)
