The paper proposes a novel framework for accelerated re-design (dimension scaling) of antenna structures using inverse surrogates. The major contribution of the work is a sensitivity-based model identification procedure, which permits a significant ...
Tomasson, Jon Atli; Koziel, Slawomir; Pietrenko-Dabrowska, Anna(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Optimization-based parameter tuning has become an inherent part of contemporary antenna design process. For the sake of reliability, it is typically conducted at the level of full-wave electromagnetic (EM) simulation models. This may incur considerable ...
Koziel, Slawomir; Pietrenko-Dabrowska, Anna(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Design of modern antennas relies-for reliability reasons-on full-wave electromagnetic simulation tools. In addition, increasingly stringent specifications pertaining to electrical and field performance, growing complexity of antenna topologies, along ...
