Abstract
Surface transverse wave (STW) devices exhibit two substantial advantages over conventional surface acoustic wave (SAW) devices. These are a substantially higher velocity and power handling capability. Each of these characteristics are often great assets in frequency control applications. However, STW devices have found little commercial application. This may be attributed to a lack of a practical and accurate analysis method. By applying the recent advances in the analysis of STW devices by Plessky (1993), Hashimoto and Yamaguchi (1994), a new COM analysis of STW devices has been developed. This new COM formalism is applied to the analysis of STW coupled resonators to demonstrate the accuracy of the method.Keywords
