Helicon

(hĕl`ĭkŏn), Gr. Elikón, mountain group, c.20 mi (30 km) long, central Greece, in Boeotia; it rises to 5,736 ft (1,748 m). Helicon formed part of the border between ancient Boeotia and Phocis. In Greek legend it was the abode of the Muses and sacred to Apollo. The fountains of Hippocrene and Aganippe are on the slopes of Mt. Helicon. The temple of the Muses was situated in the eastern part of the mountain, at the foot of which were Thespiae and Ascra, home of Hesiod.

The helicon frequency [omega] is of RF range and [[omega].
the frequency modulation of helicon wave and modulation of magnetic field are equivalent.
The real part of the ratio I/E is equal to the conductivity of semiconductor plasma and the imaginary part is responsible for helicon wave propagation (effective dielectrical constant).
