Adjoint Sensitivity Analysis of High Frequency Structures with MATLAB‡
The ACES Series on Computational Electromagnetics and Engineering (CEME) Andrew F. Peterson, PhD – Series Editor The volumes in this series encompass the development and application of numerical techniques to electrical systems, including the modeling of electromagnetic phenomena over all frequency ranges and closely related techniques for acoustic and optical analysis. The scope includes the use of computation for engineering design and optimization, as well as the application of commercial modeling tools to practical problems. The series will include titles for undergraduate and graduate education, research monographs for reference, and practitioner guides and handbooks. Series Editorial Board Andrew F. Peterson – Series Editor, Georgia Institute of Technology Atef Z. Elsherbeni – Associate Series Editor, Colorado School of Mines James C. Rautio, Associate Series Editor, Sonnet Software, Inc.
