  Publikacja

  • N. Leszczynska
  • M. Klinkosz
  • M. Mrozowski

  - Rok 2016

  In this paper, we present a fast technique for an automated design of microwave filters in substrate integrated wave (SIW) technology. The proposed methodology combines the space mapping technique with a cost function defined using the location of complex zeros and poles of filter’s transfer and reflection function and uses a rectangular waveguide as a surrogate model. The effectiveness of the proposed technique is presented with...

  Publikacja

  • A. Bekasiewicz
  • S. Kozieł

  - Metrology and Measurement Systems - Rok 2019

  Compact radiators with circular polarization are important components of modern mobile communication systems. Their design is a challenging process which requires maintaining simultaneous control over several performance figures but also the structure size. In this work, a novel design framework for multi-stage constrained miniaturization of antennas with circular polarization is presented. The method involves sequential optimization...

  • Q. Cheng
  • S. Kozieł

  - SENSORS - Rok 2019

  In order to minimize the number of evaluations of high-fidelity (“fine”) model in the optimization process, to increase the optimization speed, and to improve optimal solution accuracy, a robust and computational-efficient multi-fidelity local surrogate-model optimization method is proposed. Based on the principle of response surface approximation, the proposed method exploits the multi-fidelity coarse models and polynomial interpolation...

• On Improved-Reliability Design Optimization of High-Frequency Structures Using Local Search Algorithms

  Publikacja

  • S. Kozieł
  • A. Pietrenko-Dąbrowska
  • P. Płotka

  - IEEE Access - Rok 2022

  The role of numerical optimization has been continuously growing in the design of high-frequency structures, including microwave and antenna components. At the same time, accurate evaluation of electrical characteristics necessitates full-wave electromagnetic (EM) analysis, which is CPU intensive, especially for complex systems. As rigorous optimization routines involve repetitive EM simulations, the associated cost may be significant....

• Design of power cable lines partially exposed to direct solar radiation – special aspects

  Publikacja

  • S. Czapp
  • S. Szultka
  • A. Tomaszewski

  - ENERGIES - Rok 2020

  Power cable lines are usually buried in the ground. However, in some cases, their ending sections are mounted along the supports of overhead lines. This leads to a situation where the cables are exposed to direct solar radiation and, consequentially, overheat. The paper presents the advanced computer modelling of power cables’ heating, considering their insolation as well as the effect of wind. The temperature and current-carrying...

  • M. Belen
  • N. Calik
  • S. Kozieł

  - IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION - Rok 2022

  Reflectarrays (RAs) have been attracting considerable interest in the recent years due to their appealing features, in particular, a possibility of realizing pencil-beam radiation patterns, as in the phased arrays, but without the necessity of incorporating the feeding networks. These characteristics make them attractive solutions, among others, for satellite communications or mobile radar antennas. Notwithstanding, available microstrip...

  - Rok 2019

  Designing a concrete mix is a process of synthesizing many components, it is not a simple process and requires extensive technical knowledge. The design process itself focuses on obtaining the required strength of concrete. Very often designing a concrete mix takes into account the need to maintain the proper water-demand and frost-resistance features. The parameters that influence the concrete class most significantly are the...

  Publikacja

  • A. Bekasiewicz
  • S. Kozieł
  • W. Zieniutycz

  - Rok 2014

  A computationally efficient procedure for multi-objective optimization of antenna structures is presented. In our approach, a response surface approximation (RSA) model created from sampled coarse-discretization EM antenna simulations is utilized to yield an initial set of Pareto-optimal designs using a multi-objective evolutionary algorithm. The final Pareto front representation for the high-fidelity model is obtained using surrogate-based...
