THE USE OF ANISOTROPIC DIELECTRIC MATERIALS FOR OBTAINING MUTUAL CAPACITANCE
Abstract
A generalized theoretical analysis of the anisotropy transformer and similar devices is developed. A transform-analog technique for the determination of optimum physical configurations for realization of mutual capacitance and voltage gain and for the determination of equivalent-circuit parameters is employed. The open-circuit voltage gain of the anisotropy transformer is shown to have an upper limit of unity under linear operation conditions and this demonstration is extended to include the general class of such devices. Since a linear-mode greater than unity is impossible, the non- linear properties of multi-terminal dielectric materials (specifically Rochelle salt) and their application as nonlinear elements in dielectric amplifier configurations is investigated. The use of Rochelle salt as a nonlinear element proves to be impractical and feasibility of nonlinear anisotropic coupling techniques in other oriented ferroelectric crystals is found to depend on poorly understood aspects of the macroscopic consequences of the mechanism of polarization reversal.
