3D EM data driven surrogate based design optimization of traveling wave antennas for beam scanning in X-band: an application example
Belen, Aysu; Güneş, Filiz; Palandöken, Merih; Tarı, Özlem; Belen, Mehmet Ali; Mahouti, Peyman (Springer, 2022)In this paper, design and optimization of a microstrip elliptic traveling wave antenna (TWA) are presented for the beam scanning in X-band as an application of 3D data driven surrogate based design optimization technique. ... -
Accurate Modeling of Antenna Structures by Means of Domain Confinement and Pyramidal Deep Neural Networks
Koziel, Slawomir; Çalık, Nurullah; Mahouti, Peyman; Belen, Mehmet Ali (Institute of Electrical and Electronics Engineers Inc., 2022)The importance of surrogate modeling techniques has been gradually increasing in the design of antenna structures over the recent years. Perhaps the most important reason is a high cost of full-wave electromagnetic (EM) ... -
Accurate Modeling of Frequency Selective Surfaces Using Fully-Connected Regression Model With Automated Architecture Determination and Parameter Selection Based on Bayesian Optimization
Çalık, Nurullah; Belen, Mehmet Ali; Mahouti, Peyman; Koziel, Slawomir (Institute of Electrical and Electronics Engineers Inc., 2021)Surrogate modeling has become an important tool in the design of high-frequency structures. Although full-wave electromagnetic (EM) simulation tools provide an accurate account for the circuit characteristics and performance, ... -

Gain Enhancement of a Traditional Horn Antenna using 3D Printed Square-Shaped Multi-layer Dielectric Lens for X-band Applications
Belen, Aysu; Mahouti, Peyman; Güneş, Filiz; Tarı, Özlem (Applied Computational Electromagnetics Society Journal, 2021)In this work, gain of a traditional horn antenna is enhanced up to 2.9 dB over X-band using 3D printed square-shaped multi-layer lens. For this purpose, firstly the multi-layer lenses are designed using Invasive Weed ... -
Improved Modeling of Microwave Structures Using Performance-Driven Fully-Connected Regression Surrogate
Koziel, Slawomir; Mahouti, Peyman; Çalık, Nurullah; Belen, Mehmet Ali; Szczepanski, Stanislaw (Institute of Electrical and Electronics Engineers Inc., 2021)Fast replacement models (or surrogates) have been widely applied in the recent years to accelerate simulation-driven design procedures in microwave engineering. The fundamental reason is a considerable-and often prohibitive-CPU ... -
Microstrip leaky wave antenna for wide range of beam scanning in X band
Belen, Aysu; Güneş, Filiz; Belen, Mehmet Ali; Mahouti, Peyman (Wiley, 2021)In this work, design of a pattern reconfigurable antenna is presented for X-band applications as a leaky wave antenna (LWA) realization. Due to the advantages of simple design schematic, low profile, and easy impedance ... -
Surrogate Based Design Optimization of Multi-Band Antenna
Tarı, Özlem; Belen, Aysu; Mahouti, Peyman; Belen, Mehmet Ali (Institute of Electrical and Electronics Engineers Inc., 2021)In this work, design optimization process of a multi-band antenna via the use of Artificial Neural Network (ANN) based surrogate model and meta-heuristic optimizers is studied. For this mean firstly, by using Latin-Hyper ...
