Abstract A computer simulation, based on the quasi-static Green's function model, of the passband ripples in interdigitated interdigital transducer filters is presented. Multiple-transit echo signals and electrode interactions, under the condition of poorly matched external circuits, are included in the model. A variation on the IIDT structure that suppresses the ripples is proposed.
