This experimental study shows the validity of Sheridan’s method in determining plasma density in low pressure, weakly magnetized, RF plasmas using ion saturation current data measured by a planar Langmuir probe. The ion density derived from Sheridan’s method which takes into account the sheath expansion around the negatively biased probe tip, presents a good consistency with the electron densit...

Enhancing the frequency band of electromagnetic wave is regarded as an efficient way to solve communication blackout problem. In this paper, incident raised Terahertz (THz) and radar cross section (RCS) three-dimensional conductive model calculated simulated based on Runge–Kutta Exponential Time Differencing–Finite Difference Domain method (RKETD-FDTD). Interaction THz magnetized plasma sheath ...

A two-dimensional dust crystal levitated in the sheath of a modified Gaseous Electronics Conference (GEC) reference cell is manipulated by heating or cooling the lower electrode. The dust charge is obtained from top-view pictures of the crystal using a previously developed analytical model. By assuming a simple force balance, and measuring the radial confining force, the vertical electric field...
