INDUSTRIAL APPARATUS FOR APPLYING RADIO-FREQUENCY ELECTROMAGNETIC FIELDS TO SEMICONDUCTIVE DIELECTRIC MATERIALS

摘要

Industrial apparatus for applying radio-frequency electromagnetic fields to semiconductive dielectric materials comprises a radio-frequncy voltage generator (10) and an applicator device (1) for applying radio-frequncy electromagnetic fields. The applicator device (1) comprises a plurality of electrodes (12, 13, 14, 15) electrically connected to the electrical generator (10) for generating between then a radio-frequency electromagnetic field with electrical and magnetic components arranged in a preferential direction. The applicator device (1) further comprises at least one pair of equipotential electrodes (12, 14) substantially aligned in the preferential direction and material transportation means (32) for housing and transporting semiconductive dielectric material within the applicator device (1) in a direction substantially parallel to the preferential direction.
