Abstract :
A universal approach to SAW device modeling is generalized consistently with an aim to describe a great variety of multi-track architectures. Crosstalk interactions (either acoustic or electrical ones) in systems containing an arbitrary number of non-identical tracks are taken into account. These tracks may influence each other either due to waveguide coupling or due to re-radiation of SAW beams from one track to another by transducers (IDTs, SPUDTs, or R-SPUDTs) placed in different channels and electrically connected in parallel. Parasitic diffraction crosstalk may be considered in the same modeling manner too, neglecting the waveguide and re-radiation effects
