Analysis and implementation of prediction models for the design of fixed terrestrial point-to-point systems
Göktaş, Polat (Bilkent University, 2015)In this study, propagation link analysis and implementation of prediction models for the design of fixed terrestrial point-to-point systems are aimed. Different propagation models in the literature are examined as case ... -
Development of an experimental image processing tool and flow-cytometry based electromagnetic scattering analysis for medical diagnosis of red blood cell pathology
Göktaş, Polat (Bilkent University, 2020-08)The morphological, biophysical and biochemical properties of biological cells are critical markers for many fields, including life sciences, medical diagnosis, etc. Label-free, high-throughput classification and detection ... -
Electromagnetic scattering by several 2-D single biological cell models
Göktaş, Polat; Sukharevsky, I. O.; Altıntaş, Ayhan (IEEE, 2018-01)The electromagnetic 2-D scattering from a single biological cell is analyzed by using Muller boundary integral equation (MBIE) method. The accuracy and smoothness of the solution are improved by applying Nystrom-type ... -
Image-Based flow cytometry and angle-resolved light scattering to define the sickling process
Göktaş, Polat; Sukharevsky, I.; Larkin, S.; Kuypers, F.; Yalçın, Ö.; Ayhan, Altıntaş (International Society for Advancement of Cytometry, 2019)Red blood cells (RBCs) from sickle cell patients exposed to a low oxygen tension reveal highly heterogeneous cell morphologies due to the polymerization of sickle hemoglobin (HbS). We show that angle‐resolved light scattering ... -
Mikrodalga karasal radyo link analiz ve simülasyonlarının Rec. ITU-R P.530 tavsiyesine uygun olarak gerçeklenmesi
Göktaş, Polat; Topçu, Satılmış; Karaşan, Ezhan; Altıntaş, Ayhan (URSI, 2014)Bu çalışmada, NATO Band 3+ (1350 – 2690 MHz) ve NATO Band 4 (4400 – 5000 MHz) frekanslarında çalışan karasal mikrodalga radyo linklerin analizi için gerekli olan yansıma noktası hesabının iyileştirilmesi ve yansımadan ... -
A new approach to diffraction modelling for line-of-sight (LOS) paths
Topçu, Satılmış; Göktaş, Polat; Karasan, Ezhan; Altıntaş, Ayhan (IEEE, 2015)In this paper, we present a new knife-edge diffraction method based on Bullington method for the terrestrial line-of-sight (LOS) paths. The diffraction loss of our new knife-edge diffraction method is compared with the ... -
Sabit karasal mikrodalga LOS/NLOS radyo linklerin enterferans analizi
Göktaş, Polat; Topcu, Satılmış; Karaşan, Ezhan; Altıntaş, Ayhan (IEEE, 2015-05)Bu çalışmada, NATO Band 3+ (1350-2690 MHz) ve NATO Band 4 (4400-5000 MHz) frekans bantlarında çalışan sabit karasal mikrodalga LOS (karasal görüş çizgisi)/ NLOS (ufuk ötesi) radyo linkleri için enterferans modellenmesi ele ... -
Sabit karasal noktadan-noktaya sistemlerin çok yollu sönümlenmesini azaltmak için uzaysal çeşitleme tekniğini değerlendirme
Göktaş, Polat; Topcu, Satılmış; Karaşan, Ezhan; Altıntaş, Ayhan (IEEE, 2015-05)Çok yollu sönümlenme mekanizması, 10 GHz altındaki frekanslarda çalışan sabit karasal mikrodalga görüş çizgisi radyo linkleri için belirleyici yayılım faktörüdür. Çok yollu yayılımdan dolayı sönümlenme karasal görüş çizgisi ... -
Short-term propagation measurements and modeling for terrestrial line-of-sight links
Göktaş, Polat; Topçu, Satılmış; Karasan, Ezhan; Altıntaş, Ayhan (IEEE, 2016)This paper presents a propagation prediction technique to predict propagation mechanisms for fixed terrestrial line-of-sight (LOS) radio links, especially proposed for rural environments. We report the results of a short-term ...
