Abstract :
The electrostatic problem is considered for an arbitrary planar system of conducting strips with given electric potentials. The spatial spectrum of the electric charge distribution in the plane of the strips is evaluated. This spatial spectrum is important in the analysis of surface acoustic wave devices. A new formulation of the scattering problem is presented convenient for computations. Examples confirm the quasiperiodic model of an IDT
