Coupled slow-wave structures

A generalized model of the coupled slow-wave structures (CSWS) formed by placed in parallel or coaxially impedance conductors, had been considered. Substituting obtained equivalent parameters in the «truncated» long-line dispersion equation made it possible deriving a dispersion equation and an expression for the opposite phase wave slowing down. It follows from the obtained relations that independently on the specific configuration of the impedance conductors, slowing of the opposite-phase wave in the CSWS may exceed many times slowing in one impedance conductor while saving a large enough wave impedance and a small loss in the conductors. It has been shown that the electric field energy concentration between impedance conductors and the magnetic field energy concentration outside conductors provides the significant increase in the effectiveness of RF heating and measuring providing the possibility of developing novel technologies and devices for industrial and medical applications.
