In order to obtain high output powers from transversely excited pulsed lasers it is important to have a very uniform energy loading of the active gas medium. That is why there is a need for specially contoured electrodes which produce a very uniform field strength over a certain amount o f surface. A number o f authors have given solutions to this problem. Up to now, Rogowski profiles [ 1] are ...

OBJECTIVE High resolution visual prostheses require dense stimulating arrays with localized inputs of individual electrodes. We study the electric field produced by multielectrode arrays in electrolyte to determine an optimal configuration of return electrodes and activation sequence. APPROACH To determine the boundary conditions for computation of the electric field in electrolyte, we assess...

In order to obtain high output powers from transversely excited pulsed lasers it is important to have a very uniform energy loading of the active gas medium That is why there is a need for specially contoured electrodes that produce a very uniform field-strength distribution over a certain amount of surface. A number of authors tried to solve this problem. Rogowski’s [ 1 ] and Chang’s [2] profi...

Progress in interventional medicine is associated with the development of more delicate and less invasive surgical procedures, which requires more precise and less traumatic, yet affordable, surgical instruments. Previously we reported on the development of the pulsed electron avalanche knife for dissection of soft tissue in liquid media using the 100 ns plasma-mediated electric discharges appl...

An electric field in the dielectric barrier electrode system is necessary for ozone production because produced by discharge of O2 under a high-intensity field. The gas plasmas contain energetic particles, such as electrons, ions, atoms, and radicals. recombination O atom plasma will form O3. In this paper, dependence DC formation on geometry gap between electrodes materials were examined using...

Uniform deposition of nanofibers in the massive electrospinning process is critical in the industrial applications of nanofibers. Tip-Induced Electrospinning (TIE) is a cost-effective large-scale nanofiber-manufacturing method, but it has poor deposition uniformity. An auxiliary conductive electrode connected to the emitting electrode was introduced to improve the deposition uniformity of the n...
