In a previous work, the addition of basic screened Coulombic electrostatic forces to an existing commercial discrete element modeling (DEM) software was reported. Triboelectric experiments were performed to charge glass spheres rolling on inclined pl

Theoretical and experimental work has been performed pursuant to incorporating electrostatic forces into a commercial Discrete Element Modeling (DEM) software package. This DEM software is used to model the trajectories of large numbers of particles

We have measured the two‐photon absorption coefficent at 0.527 μm to be 1.8±0.4×10−3 cm/GW in a germanium‐doped silica fiber. Using absorption and luminescence measurements we estimated the two‐photon absorption coefficient at 1.053 μm to

The effect of a thin, dielectric buffer layer on coplanar electrode structures is examined. The buffer layer is placed between the metal electrodes and the dielectric substrate. It is seen to have a significant effect on the charge distribution, fiel

A numerical model for photoinduced second-harmonic generation in glass is presented. We use the beam-propagation method (BPM) to model the effects of focusing a laser beam and its second harmonic into a bulk sample of glass. The two-color optical fie

A finite-difference implementation of the beam propagation method (BPM) is used to solve the paraxial, scalar wave equation with a nonlinear source term. A transparent boundary condition capable of handling asymmetric modes is incorporated in the fin

Tribocharging of particles is common in many processes including fine powder handling and mixing, printer toner transport and dust extraction. In a lunar environment with its high vacuum and lack of water, electrostatic forces are an important factor

In this paper we present experimental evidence for the creation of defects in Ge doped silica by exposure to intense visible or UV light. The presence of the defects is detected by an increase in two photon absorption at 1053 nm and an increase in ph

We investigate the process by which induced static electric fields are produced in waveguide materials during SHG. Most of the models for the production of these fields rely on a photoionization process within the waveguide which has a preferential p
