Abstract
This chapter describes the theory and modeling of IDTs employed for SAW excitation and detection. First, the delta-function model is detailed. Then the effects of peripheral circuits are discussed. Unidirectional transducers (UDTs) are also included in the discussion, and the p matrix method [1] is introduced as an effective tool for the characterization of UDTs.
Keywords
