plasma_frequency¶

Physics.plasma_frequency(electron_density)¶

Radial plasma frequency (rads/sec)

To get cyclic plasma frequency (Hz) divide by 2*pi

Examples

In [1]: import Physics as P In [2]: P.plasma_frequency(1.)/(2*pi) Out[2]: 8978.6637622453945

If electron density is in electrons/m^3, divide by 1e6.

In [3]: P.plasma_frequency(1.e-6)/(2*pi) Out[3]: 8.9786637622453949 Reference ========= http://www.carnicom.com/plasma1.htm
