FORMATION METHOD OF TWO-DIMENSIONAL LINEAR HIGH-FREQUENCY ELECTRIC FIELD, AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2013 - IPC H01J49/22 

FIELD: electricity.

SUBSTANCE: proposed method is based on formation on flat surfaces of discrete linear distributions of high-frequency potential by means of parallel capacitance dividers. The system consists of three flat electrodes, one electrode is earthed and two other electrodes have opposite-phase discrete linear distributions along one axis of high-frequency potentials. Discrete electrodes are made of thin dielectric plates with conducting surfaces applied to them. Outer surfaces are separated diagonally into two halves, one of which is earthed, and high-frequency potentials are applied to the other ones. Inner surfaces that are not connected galvanically to other parts of an analyser, are formed of conducting strips uniformly distributed along one axis. Capacitance dividers of high-frequency voltage with a division coefficient linearly changing along one coordinate are formed between inner and outer conducting surfaces.

EFFECT: improvement of design of electrode systems for formation of two-dimensional linear high-frequency electric fields for the purpose of achieving high accuracy of implementation of their design geometry by means of modern technologies at manufacture.
