Professor Spielman joined the Naval Research Laboratory (NRL) in 1971 as a research electronics engineer in the Microwave Techniques Branch and pursued his career at NRL for 17 years. During this period, he was promoted to various positions and ultimately to Head of the Microwave Technology Branch in 1984. In this capacity, he led a group of 20 researchers investigating a wide range of microwave semiconductor and superconductor devices and related integrated-circuit components. He served in this position until he left to join the Department of Electrical Engineering at Washington University in 1987 as Chair and faculty member. He served as Chair of the Department of Electrical Engineering from 1987 to 2002.
Professor Spielman has held numerous offices in the IEEE, including President of the IEEE Society on Microwave Theory and Techniques (MTT-S) in 1988. He served as guest editor of various publications, including special issues of the IEEE Proceedings and the IEEE-MTTS Transactions. He was elected Fellow in the IEEE in 1995 and Life Fellow of the IEEE in 2007. In 2002, Professor Spielman was presented with the Third Miliennium Medal by the IEEE.
Professor Spielman's research interests include applied electromagnetic and microwave theory, numerical solution of electromagnetic problems, metamaterial applications, and electronics packaging.
Currently, Professor Spielman is performing research on the application of metamaterials. Early work involved the investigation of stability issues in time-domain simulations of electromagnetic behavior in this new class of materials. More recently, his group is focusing on radiation and scattering from surfaces composed of composite meta- and traditional-materials.
Other research involves the synthesis of microwave packaging features through electromagnetic solutions. This work involves developing mathematical formulations of 3-dimensional, electromagnetic problems involving arbitrarily-configured conductors and dielectrics. The formulation is then reduced to a computationally useful matrix analysis employing the method of moments. This analysis is then cast as an optimization problem by defining a cost function that incorporates specified performance at generalized ports for the configuration.
