Research Highlights – August

Abstract

Provide an outstanding educational program that enables our graduates to become leaders in their professions by imparting fundamental principles, skills, and tools to innovate and excel.Pursue the discovery of fundamental knowledge and its applications to position the department among the leaders in research.Respond to the needs of the State of Iowa and the nation by building a strong outreach program that serves industry and the engineering profession. HONORS and AWARDS ENDOWED CHAIRS AND PROFESSORSHIPSDavid FELLOWS ADVANCED ELECTRONICS AND MATERIALS AEMThe Advanced Electronics and Materials group includes three synergistic engineering areas represented by the Center for Nondestructive Evaluation, the Microelectronics Research Center, and the Analog and Mixed-Signal VLSI Design Center. Many ECpE faculty work at these centers, while others work wholly within the ECpE department.Research includes three-dimensional electromagnetic field simulation and modeling, nondestructive material evaluation instrumentation and research, advanced materials processing, thin film semiconductor devices, photonic bandgap materials and devices, solar energy conversion, magnetics, and mixed-signal VLSI design from low frequencies up through millimeter wavelengths.Robert Weber, Chair NONDESTRUCTIVE EVALUATION AND ELECTROMAGNETICS Primary MembersJohn AEM FAST AND EFFICIENT ALGORITHMS IN COMPUTATIONAL ELECTROMAGNETICSThe goal of this project is to explore and develop fast and efficient algorithms in computational electromagnetics in order to solve scattering and radiation from complex, large-scale objects. As a principal research scientist in the Center for Computational Electromagnetics at the University of Illinois, the PI developed a three-dimensional fast multipole method, a multilevel fast multipole algorithm, and the fast Illinois solver code (FISC) for use in largescale electromagnetic analysis. To date, more than 400 copies of FISC have been distributed to government and industrial users. In addition, higherorder methods for applying the method of moments have been developed for solving integral equations, resulting in faster convergence, less CPU time, and fewer memory requirements. We also developed fast algorithms for lowfrequency applications of EMC/EMI and approaches for broadband simulations of electromagnetic scattering using frequency domain methods. We are developing well-conditioned integral equations, fast and efficient algorithms for electromagnetic scattering and radiation, light scattering from biological cells, and de-embedding algorithms and electromagnetic modeling and simulations for interconnects and RF components over conducting silicon.
