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, ... -
A compact triband antipodal Vivaldi antenna with frequency selective surface inspired director for IoT/WLAN applications
Güneş, Filiz; Evranos, İlhan Ömer; Belen, Mehmet Ali; Mahouti, Peyman; Palandöken, Merih (Springer, 2021)In this paper, an antipodal triband Vivaldi antenna operating in 2.4/5.2/5.8 GHz bands has been presented for WLAN/IoT applications. The proposed antipodal Vivaldi antenna has meander line shaped slotted lines, which are ... -
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 ...
