Complex image method for RF antenna-plasma inductive coupling calculation in planar geometry. Part II: measurements on a resonant network

Ivo Furno, Alan Howling, Philippe Frédérique Bruno Guittienne, Rémy Jacquier

Measurements and analysis of a radio-frequency planar antenna are presented for applications in inductively-coupled plasma processing. The network of inductive and capacitive elements exhibits high currents under resonance which are efficient for plasma ge ...

Analysis of resonant planar dissipative network antennas for rf inductively coupled plasma sources

Christoph Hollenstein, Alan Howling, Philippe Frédérique Bruno Guittienne

The analysis of a radio-frequency (RF) planar antenna is presented for applications in plasma processing. The antenna is a network of elementary meshes composed of inductive and capacitive elements which exhibits a set of resonant modes. The high currents ...

Direct current breakdown in gases for complex geometries from high vacuum to atmospheric pressure

Christoph Hollenstein, Alan Howling, Ralph Schnyder

The demand for improved performances of power transmission devices requires ever smaller dimensions and higher working voltages which lead to increased risk of breakdown, for example, in satellite slip rings. Previous works are mostly limited to breakdown ...
