FREQUENCY-TUNABLE DIELECTRIC RESONATOR

摘要

The invention concerns a dielectric resonator for electromagnetic waves comprising at least one junction formed by an interface zone between two materials with different dielectric properties one of which is a semiconductor material, and a polarizing circuit (11, 14, 17) capable of applying a polarizing voltage (Up) of at least one junction, called polarized junction, said polarizing voltage (Up) being adapted to modify the spatial distribution of the electric charges at each polarized junction to produce frequency tuning while maintaining a permissible value of the quality coefficient Q of the resonator.
