Abstract :
An easy-to-implement, accurate, and fast method to calculate 2-D quasi-static capacitance and inductance of electrodes in SAW devices is presented. The method is outlined by considering electrodes with any cross-section geometries in dielectric environment, consisting of two anisotropic materials with a plane interface. The analysis allows the inclusion of arbitrarily shaped metallic packages. A significant shift of charges on enclosures, due to the substrate anisotropy, is observed.<>
