Paper Abstract

We describe a computational method for calculating the electric field, generated by a periodical set of electrodes, that are placed on the surface(s) of a 9/65/35 PLZT electro-optic ceramics layer. This method is based on the introduction of two auxiliary functions that describe the density of electric charge distribution on the electrodes with different potentials. The problem is then reduced to the solution of the two integral equations in these functions. The coordinate transforms of each of the two equations, which map electrode areas onto the whole period, modify these integral equations into two coupled infinite sets of algebraic equations for coefficients of expansion into a Fourier series of auxiliary functions. For the new sets of expansion coefficients, the sets of equations become decoupled ones. These equations were solved numerically by cutting to a finite number of equations. With the help of this method, the three schemes of electrode connections were analyzed. The dependences of the half-wave voltage and the switching energy on the electrode spatial frequency and on the relative electrode width were determined. These dependences give the possibility to obtain the optimal electrode pattern of the schemes and find out the optimal scheme of electrode connections.
