Surface Acoustic Wave(SAW) devices have been used widely in Radio Frequency(RF) circuits of mobile communication equipments such as cellular phones. In this study, an optimal design technique of multifunctional SAW devices is developed for reducing the number of electronic parts used in RF circuits. The results of this study can be summarized by the following three points. 1) The structural design of a SAW filter is formulated as a three-objective optimization problem. Then a Multi-Objective Evolutionary Algorithm(MOEA) based on the latest EA, i. e., Differential Evolution(DE), is applied to the optimization problem. In order to analyze the relationship between the structure of electrodes and the device function, a set of solutions obtained by MOEA is evaluated statistically by using the principal component analysis. 2) A new MOEA is proposed for solving the multi-objective optimization problems which have more than four objectives. A fast approximation algorithm for the exclusive hypervolume is used by the new MOEA as the criterion of solutions. 3) In order to utilize multi-core CPUs for the design of multifunctional SAW devices, a concurrent program of DE is developed.

表面声波（SAW）器件广泛应用于移动通信设备（如蜂窝电话）的射频（RF）电路中。为了减少射频电路中使用的电子元件数量，本研究开发了一种多功能SAW器件的优化设计技术。本研究的结果可以概括为以下三点。1)将声波滤波器的结构设计表述为一个三目标优化问题。在此基础上，提出了一种基于差分进化的多目标进化算法（MOEA）。为了分析电极结构与器件功能之间的关系，利用主成分分析对MOEA得到的一组解进行了统计评价。2)针对4个以上目标的多目标优化问题，提出了一种新的MOEA。该模型采用了一种快速逼近算法作为解的判据。3)为了利用多核cpu设计多功能SAW器件，开发了一个DE并发程序。
