A Reduced Basis Method for Microwave Semiconductor Devices with Geometric Variations

Purpose - The Reduced Basis Method (RBM) generates low-order models of parametrized PDEs to allow for efficient evaluation of parametrized models in many-query and real-time contexts. The purpose of this paper is to investigate the performance of the RBM in microwave semiconductor devices, governed by Maxwell's equations. Design/methodology/approach - The paper shows the theoretical framework in which the RBM is applied to Maxwell's equations and present numerical results for model reduction under geometry variation. Findings - The RBM reduces model order by a factor of $1,000 and more with guaranteed error bounds. Originality/value - Exponential convergence speed can be observed by numerical experiments, which makes the RBM a suitable method for parametric model reduction (PMOR). © Emerald Group Publishing Limited.
