where:
fp = Plasma frequency (Hz)
ne = Electron density (electrons/m³)
e = Elementary charge (1.602 x 10-19 C)
ε0 = Permittivity of free space (8.854 x 10-12 F/m)
me = Electron mass (9.1094 x 10-31 kg)
- Plasma is uniform and electron density is consistent.
- Temperature effects on the electron distribution are neglected.
- Collisional effects between electrons and ions are negligible.
- The plasma remains incompressible.
