(Institute of Electrical and Electronics Engineers (IEEE), 2020-05-27)Utilization of fast surrogate models has become a viable alternative to direct handling of full-wave electromagnetic (EM) simulations in EM-driven design. Their purpose is to alleviate the difficulties related to high computational cost of multiple ... -
(2019-03-01)In this work, we theoretically model the time-dependent transport through an asymmetric double quantum dot etched in a two-dimensional wire embedded in a far-infrared (FIR) photon cavity. For the transient and the intermediate time regimes, the current ...

(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 ...

Rapid Optimization of Compact Microwave Passives Using Kriging Surrogates and Iterative Correction (Institute of Electrical and Electronics Engineers (IEEE), 2020)Design of contemporary microwave components is & x2014;in a large part & x2014;based on full-wave electromagnetic (EM) simulation tools. The primary reasons for this include reliability and versatility of EM analysis. In fact, for many microwave ...

(Institute of Electrical and Electronics Engineers (IEEE), 2024)Molecular dynamics simulations, with full Coulomb interaction, are used to model short-pulse photoemission from a finite area in a microdiode. We demonstrate three emission regimes, source-limited emission, space-charge-limited emission for short pulses, ...
