| Outline of Final Research Achievements |
Recently, Surface Acoustic Wave (SAW) devices, which have been widely used in Radio Frequency (RF) circuits of mobile communication equipments, are required to be further miniaturized. On the other hand, Multi-Objective Design Exploration (MODE) is a design support approach that efficiently extracts the useful information from a number of non-dominated solutions obtained through Evolutionary Multi-criterion Optimization (EMO).
In this study, a new design support approach called precision ensuring MODE is proposed and applied to the structural design of SAW devices in which various uncertainties incidental to miniaturization are considered. The results of this study are summarized as follows: Developments of 1) Simulators of several SAW devices, 2) A new EMO algorithm applicable to many-objective optimization problems, and 3) A precision ensuring evaluation technique of uncertainty based on prediction interval. 4) Acquirement of knowledge that is useful to miniaturize SAW devices.
