High‐Intensity Laser Triggered Proton Acceleration from Ultrathin Foils
(WILEY‐VCH Verlag, 2013-02)
The recently developed PIC code MANDOR features arbitrary target design including 3D preplasma and the 6‐component laser fields of a tightly focused laser beam. The 3D simulations have been performed to model recent HERCULES ...
Modular optics interferometer
(Elsevier, 1977-06)
A waveguide interferometer is assembled using holographically formed optical elements that are constructed as individual components and can be selectively attached to an optical waveguide. The interferometer is very rugged ...
Diffusion MRI in early cancer therapeutic response assessment
(WHOWiley Periodicals, Inc., 2017-03)
Analytic MODFET models beyond the triangular well approximation
(Elsevier, 1990-07)
A new approach to modeling normal interface modulation doped field-effect transistors (MODFETs) is presented in which the 2-D electron gas density is integrated along the channel instead of the channel potential. With this ...
Triplet state EPR spectra
(Elsevier, 1984-03)
A characterization of triplet EPR spectra in terms of the eight phenomenological parameters of the spin Hamiltonian is given. Closed-form solutions for the three possible resonant fields between triplet energy levels are ...
Modulation of twin-emitter semiconductor lasers beyond the frequency of relaxation oscillations
(Elsevier, 1991-04-15)
Self-modulation above the relaxation oscillation frequency has been previously observed in a phased-array semiconductor lasers. Rate equations for a twin-emitter phased-array semiconductor laser are used to show that active ...
Nonholonomic Virtual Constraints and Gait Optimization for Robust Robot Walking Control.
(2016)
Bipedal locomotion is well suited for mobile robotics because it promises to allow robots to traverse difficult terrain and work effectively in man-made environments. Despite this inherent advantage, however, no existing ...
Determining the phase of line objects by measuring their intensity in dark field and bright field illumination
(Elsevier, 1973-06)
The in situ phase of a transparent line object can be calculated from measurements of its bright field and dark field intensity. If the sampling aperture is a slit, the background can be subtracted out for increased accuracy. ...
Power limitations in BARITT devices
(Elsevier, 1976-09)
The results of a large-signal numerical simulation of the BARITT device using a single-carrier model are given to illustrate the basic transport mechanisms involved in the device. The results of existing first-order small- ...
