(ACM Press, 2018)In many domains, applications have a lifetime of several years, and evolve with new technologies, changing requirements and user behavior. Simulators have been used for training for decades and have evolved in different directions. To learn how ... -
(Institute of Electrical and Electronics Engineers (IEEE), 2020)Design of a compact wideband circularly polarized (CP) multiple-input multiple-output (MIMO) antenna with polarization diversity is proposed and characterized for off-body communication. The antenna is based on a simple coplanar waveguide (CPW)-fed ...
-
(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 ...
-
(MDPI AG, 2020-04-20)Parameter optimization, also referred to as design closure, is imperative in the development of modern antennas. Theoretical considerations along with rough dimension adjustment through supervised parameter sweeping can only yield initial designs that ...
-
(MDPI AG, 2019-07-11)In this article, a generalized sequential domain patching (GSDP) method for efficient multi-objective optimization based on electromagnetics (EM) simulation is proposed. The GSDP method allowing fast searching for Pareto fronts for two and three ...
-
(Elsevier BV, 2020-10)Flow conditions in complex terrains such as fjords are highly three-dimensional and thus not properly captured by the wind flow models developed for homogenous terrains. In the present study, we explore the potential of computational fluid dynamics ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2020)Design of contemporary antennas necessarily involves electromagnetic (EM) simulation tools. Their employment is imperative to ensure evaluation reliability but also to carry out the design process itself, especially, the adjustment of antenna dimensions. ...
-
(American Chemical Society (ACS), 2018-02-12)We propose an experimentally friendly scheme for trapping quasi-relativistic electrons in graphene by an electromagnetic beam with circular polarization and a spatially inhomogeneous profile with an intensity dip. The trapping is achieved due to the ...

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 ...

(Háskólinn í Reykjavík, 2012-06-25)The aim of General Game Playing (GGP) is to create intelligent agents that automatically learn how to play many different games at an expert level without any human intervention. One of the main challenges such agents face is to automatically learn ...
-
(MDPI AG, 2019-04-15)Design of antennas for the Internet of Things (IoT) applications requires taking into account several performance figures, both electrical (e.g., impedance matching) and field (gain, radiation pattern), but also physical constraints, primarily concerning ...
