Abstract
The effects of dimensional resonance of magnetoplasmic waves in semiconductors were investigated. It was demonstrated that these effects could be used to measure the strong magnetic fields. Possible ways to design contactless magnetic field sensors operating at room or at cryogenic temperature, such as that of liquid nitrogen are discussed. It has been shown that for strong field sensor a semiconductor material of high carrier mobility μ, density N and compact RF system for registration of dimensional resonance of magnetoplasmic waves in helicon resonator is needed.
