Abstract
An easy-to-use closed-form expression is reported which given the attenuation and the phase velocity of the acoustic-surface-wave eigenmodes of the uniform multistrip coupler consisting of resistive strips. A computer program has been written to implement the numerical calculation of output power, group delay and the sensitivity of output amplitude with respect to changes in the metallisation ratio.
