Anyone know of any on-line calculators or freeware for calculating the resonant vibrations of an aluminuim plate driven in the centre and clamped around the edges?
I've used Alumina for ballasting electrodes in an RF plasma generator. BN has some better mechanical and thermal properties I could use. How does it repond to RF fields?<br>
I've also seen a material called Shapal-M (which is AlN and BN mixture) - any knowledge of use in RF apps?
I'd like to measure the temperature near a RF plasma generated with a power of 1 kW. The plasma is inside a low pressure aluminium chamber. I've used liquid crystal temp "badges" that change colour. Would like something more real time.
