Journal ArticleDOI
Alignment of particles in microfluidic systems using standing surface acoustic waves
Christopher D. Wood,Stephen D. Evans,John Cunningham,Richard O'Rorke,Christoph Wälti,A. G. Davies +5 more
TL;DR: In this paper, standing surface acoustic waves, formed on a single-crystal piezoelectric substrate, are used to organize micron-scale latex particles into an array comprising a series of lines in an adjacent microfluidic system.
Journal ArticleDOI
Formation and manipulation of two-dimensional arrays of micron-scale particles in microfluidic systems by surface acoustic waves
Christopher D. Wood,John Cunningham,Richard O'Rorke,Christoph Wälti,Edmund H. Linfield,A. G. Davies,Stephen D. Evans +6 more
TL;DR: In this paper, a two-dimensional concentration and manipulation of micron-scale particles by orthogonal, surface acoustic, standing waves is demonstrated, where the particles are organized by liquid pressure waves in a microfluidic system over a piezoelectric substrate and form a uniform twodimensional array.
Journal ArticleDOI
Terahertz emission from metal-organic chemical vapor deposition grown Fe:InGaAs using 830 nm to 1.55 μm excitation
Christopher D. Wood,O. Hatem,John Cunningham,Edmund H. Linfield,A. G. Davies,P. J. Cannard,Michael J. Robertson,D.G. Moodie +7 more
TL;DR: In this paper, the authors demonstrate the generation of broadband terahertz (THz) frequency radiation from photoconductive emitters formed from Fe-doped InGaAs (Fe:InGaAs), grown by metal-organic chemical vapor deposition, following pulsed (femtosecond) laser excitation at wavelengths ranging from 830 nm to 1.55μm.
Journal ArticleDOI
Terahertz frequency range band-stop filters
TL;DR: In this article, the authors reported the operation of band-stop filters in the terahertz (THz) frequency range, working at a center frequency of 600GHz.
Journal ArticleDOI
Terahertz vibrational absorption spectroscopy using microstrip-line waveguides
M. B. Byrne,John Cunningham,Katarzyna M. Tych,Andrew D. Burnett,Mark R. Stringer,Christopher D. Wood,L. Dazhang,M. Lachab,Edmund H. Linfield,A. G. Davies +9 more
TL;DR: In this article, a terahertz microstrip-line waveguide was used to measure absorption spectra of polycrystalline materials with a high frequency resolution (∼2 GHz) and with a spatial resolution determined by the microstrip line dimensions, rather than the free-space wavelength.
