| Term: | UpperHybridFrequency |
| Definition: |
Upper hybrid oscillations involvelongitudinal motions of electrons perpendicular to the magnetic field. Theupper hybrid frequency, ΦUH, is governed bythe relationshipΦUH^2 =Φpe^2 +Θce^2 whereΦpe is electron plasma frequency andΘce is the electron cyclotron frequency. |
