Abstract :
A field solution for the acoustic-surface-wave modes in infinite arrays of metal strips is applied to multistrip directional couplers consisting of a finite number of strips. Particular emphasis is put on the behaviour close to resonance, where the period in the array is one halfwavelength of the acoustic surface wave. Experiments on an array of 120 strips show good agreement with the theory.
