About Plasma Frequency

The plasma frequency is the natural oscillation frequency of electrons in a plasma. Electromagnetic waves with frequency below the plasma frequency cannot propagate through the plasma and are reflected.

Formula:

ωpe = √(ne·e²/(ε₀·me))

Applications:

Radio wave propagation through ionosphere
Fusion plasma diagnostics
Plasma processing in semiconductors
Plasmonics and metamaterials
