Improvement of the Harmonic Technique of Probe for Measurements

Abstract Conventional Langmuir probe techniques usually face the difficulty of being used in processing plasmas where dielectric compounds form, due to rapid failure by surface insulation. A solution to the problem, the so-called harmonic probe technique, had been proposed and shown effectiveness. In this study, the  ...

Computation of Unsteady Nonlinear Flows in Cascades Using a

A harmonic balance technique for modeling unsteady nonlinear ows in turbomachinery is presented. The analysis exploits the fact that many unsteady ows of interest in turbomachinery are periodic in time. Thus, the unsteady ow conservation variables may be represented by a Fourier series in time with spatially varying.

Direct probing of contact electrification by using optical second

Aug 14, 2015 ... Contact electrification between two different materials is one of the oldest fields of study in solid- state physics. Here, we introduced an innovative system based on optical electric-field-induced second harmonic generation (EFI-SHG) technique that can directly monitor the dynamic performance.
