This work presents an accurate surrogate model of a planar inductor realized in a 65-nm CMOS technology. The main components of our modeling approach include coarse-discretization electromagnetic simulations, kriging interpolation, and space mapping. The surrogate model constructed this way is accurate over a broad frequency range and, as showcased by our examples, can be used to perform reliable...
In this paper, computationally efficient multi-objective optimization of antenna structures is discussed. As a design case, we consider a multi-parameter planar Yagi-Uda antenna structure, featuring a driven element, three directors, and a feeding structure. Direct optimization of the high-fidelity electromagnetic (EM) antenna model is prohibitive in computational terms. Instead, our design methodology...
We review work relevant to the area covered by the transmission line matrix (TLM) method, including certain historical TLM developments and design parameter sensitivity analysis for time-domain simulations. We consider exact TLM sensitivity analysis, compare it with the finite difference approach, and demonstrate its use in accelerating design optimization. We discuss ways of using space-mapping concepts...
