9502138 Michielssen研究电磁优化和组件设计中出现的目标函数通常是高度非线性的、僵硬的、多外部的、有时是不可微的，并且几乎总是计算昂贵的评估。在电磁元件设计的背景下，通过为许多电磁系统开发基于遗传算法的全局优化器来研究遗传算法(GA)的有效性，所述电磁系统例如反射阵列、扫频光栅天线、波导组件和宽带天线系统。可以推测，该研究将为各种电磁优化问题提供新的求解技术，并为上述电磁部件带来强大、高效和系统的设计技术。这项研究还将允许根据需要优化的参数的数量和特征、正分析问题的计算复杂性以及可用的计算平台来制定关于遗传算法对其他电磁优化问题的适用性的指导方针。教育卓越教学是所有一流本科和研究生课程的重要组成部分。这位年轻的电磁学教员将致力于在接下来的几年里大幅修改一些电磁学课程，以保持和提高伊利诺伊大学香槟分校(UIUC)的本科生和研究生电磁课程的质量。最近成立的工程学院的计算科学与工程(CSE)跨学科课程将有助于实现这一目标。此外，他还将推动关于建立和促进UIUC和比利时大学工程学院之间的本科生和研究生交流计划的讨论。

9502138 Michielssen Research The objective functions that arise in the context of electromagnetic optimization and component design are often highly non-linear, stiff, multi-external, sometimes non-differentiable, and almost always computationally expensive to evaluate. the effectiveness of Genetic Algorithms (Gas) is investigated within the context of electromagnetic component design by developing global GA- based optimizers for a number of electromagnetic systems, e.g., reflect arrays, frequency scanned grating antennas, waveguide components, and broadband antennas systems. It is conjectured that the proposed research will engender novel solution techniques for a variety of electromagnetic optimization problems and bring about a number of powerful, highly efficient and systematic design techniques for a aforementioned electromagnetic components. This study will also permit the formulation of guidelines regarding the suitability of Gas for other electromagnetic optimization problems in terms of number and the character of those parameter that require optimization the computational complexity of the forward analysis problem, and the available computing platform. Education Teaching excellence is an important component of all first-class undergraduate and graduate programs. This young faculty member in electromagnetic will be committed to significantly revise a number of electromagnetics courses during the next for years in order to maintain and improve the quality of the undergraduate and graduate electromagnetic curricula at the University of Illinois at Urbans-Champaign (UIUC). The recently established College of Engineering's interdisciplinary program in Computational Science and Engineering (CSE) will instrumental in achieving the goal. Furthermore, he will foster discussions regarding the establishment and the promotion of an exchange program for undergraduate and graduate students between the Colleges of Engineering at the UIUC and Belgian universities.
