We propose a scheme that uses a two-color pulsed radially-polarized laser beam to achieve electron acceleration exceeding 90% of the theoretical energy gain limit, over twice of what is possible with a one-color beam....

Femtosecond time domain measurements can provide a powerful approach for characterizing both the nonlinear as well as linear optical properties of waveguide devices. We describe a new time division interferometry technique to perform direct measurements of the nonresonant nonlinear index of refraction in AIGaAs waveguides. In addition, femtosecond time of flight measurements permit linear properties such as absorption and dispersion to be characterized using time domain techniques. These techniques permit a comprehensive characterization of linear and nonlinear waveguide properties.
The future of biomedical imaging involves obtaining quantitative diagnostic information about tissue structure and function rather than just relying on qualitative structural assessments. Ultrasound attenuation or los...

One-dimensional migration-ohmic unipolar analysis of charge transport phenomena in series, two-region, oil-pressboard composite dielectric systems are presented in planar, coaxial cylindrical and concentric spherical electrode geometries with a step current source. Space charge limited injection solutions are presented in the steady state and transients using the method of characteristics to convert the governing partial differential equations into a set of ordinary differential equations that allow analytical solutions as a function of time and space for volume and interfacial surface charge densities, charge trajectories in the oil region, and electric field and voltage drop in oil and pressboard regions. Analytical solutions are compared with some COMSOL Multiphysics numerical solutions as a way of gaining confidence in the correctness and accuracy of our numerical solutions.
Over the past several years, the formation of nanowire heterostructures via a solid-state reaction between a semiconductor nanowire and metal contact pads has attracted great interest. This is owing to its ready appli...
