Summary:A method of analyzing a microwave acoustic wave (AW) structure comprises defining a physical model of the AW structure, partitioning the physical model into a plurality of unit blocks, identifying at least one core block within the plurality of original unit blocks, computing characteristics of each of the at least one core block, deriving characteristics for each of the original unit blocks from the computed characteristics of the core block(s), combining the original unit blocks into a single block having computed characteristics derived from the characteristics of the unit blocks, such that the single block subsumes the plurality of original unit blocks, and deriving at least one electrical response of the physical model at least partially from the computed characteristics of the single block.
