Furse, Cynthia M. | Impedance of a short dipole antenna in a magnetized plasma via a finite difference time domain model | The traditional analytical analysis of plasma probes requires the use of quasi-static approximations, while numerical methods require the use of an equivalent dispersive media, both producing a nontrivial analysis of the plasma environment. On the other hand, a few techniques that combine the plasm... | Antenna theory; finite-difference time-domain; FDTD; Plasma covered antennas; Plasma measurements | 2005-08 |

Blair, Steven | Implantable devices for optical neural interfaces | Optical neural control requires light delivery techniques dependent on the experimental goal and biological model. Several light sources and neural interfaces have been implemented featuring one or more of the fol- lowing criteria: deep illumination, specific and/or com- prehensive access, spectral ... | 2013-01-01 | |

Tasdizen, Tolga | Improving the stability of algebraic curves for applications | An algebraic curve is defined as the zero set of a polynomial in two variables. Algebraic curves are practical for modeling shapes much more complicated than conics or superquadrics. The main drawback in representing shapes by algebraic curves has been the lack of repeatability in fitting algebraic... | 2000 | |

Stringfellow, Gerald B. | Influence of Sb, Bi, Tl, and B on the incorporation of N in GaAs | GaAs:N is an interesting material for many devices due to its unique compositional variation of band gap. Small amounts of N lead to a strong decrease in band gap energy as well as lattice constant. The further addition of In or Sb leads to quaternary alloys with band gap energies below 1.4 eV latti... | Antimony; Gallium Arsenide; Nitrogen | 2002 |
