Short-time Fourier transform laser Doppler holography [PDF]
, 2013 We report a demonstration of laser Doppler holography at a sustained acquisition rate of 250 Hz on a 1 Megapixel complementary metal-oxide-semiconductor (CMOS) sensor array and image display at 10 Hz frame rate.

Frequency invariant beamforming for two-dimensional and three-dimensional arrays [PDF]
, 2007 A novel method for the design of two-dimensional (2-D) and three-dimensional (3-D)arrays with frequency invariant beam patterns is proposed. By suitable substitu- tions, the beam pattern of a 2-D or 3-D arrays can be regarded as the 3-D or 4-D Fourier ...

Brillouin Optical Correlation Domain Analysis in Composite Material Beams [PDF]
Sensors, 2017 Structural health monitoring is a critical requirement in many composites. Numerous monitoring strategies rely on measurements of temperature or strain (or both), however these are often restricted to point-sensing or to the coverage of small areas. Spatially-continuous data can be obtained with optical fiber sensors.

Magneto-resistance in a lithography defined single constrained domain wall spin valve [PDF]
, 2010 We have measured domain wall magnetoresistance in a single lithographically constrained domain wall. An H-shaped Ni nano-bridge was fabricated by e-beam lithography with the two sides being single magnetic do- mains showing independent magnetic switching.

Beam-domain hybrid time-switching and power-splitting SWIPT in full-duplex massive MIMO system
EURASIP Journal on Wireless Communications and Networking, 2018 In this paper, we consider the beam-domain hybrid time-switching (TS) and power-splitting (PS) simultaneous wireless information and power transfer (SWIPT) protocol design in full-duplex (FD) massive multiple-input multiple-output (MIMO) system, where ...

Coherent amplitude modulation of electron-beam-driven Langmuir waves [PDF]
Annales Geophysicae, 2013 A linear approach to the phenomenon of irregular amplitude modulation of beam-driven Langmuir waves, developed in a previous paper, is extended to explain periodic modulation as well.

Elastic immersive wave experimentation: Theory and physical implementation
Physical Review Research, 2019 We present a proof of concept of elastic immersive wave experimentation. A physical experiment of finite volume is connected with a numerical domain via the novel theory of immersive boundary conditions.
