Kablosuz Güç Aktarımlı Geri Saçılım Haberleşme Ağlarının Modellenmesi ve Başarım Analizi
(Fen Bilimleri Enstitüsü, 2019)
In wireless-powered communication networks, the users need to harvest enough energy from the dedicated power station or existing radio frequency signal in order to actively transmit data. This requires the user to dedicate ...
Dünya Yüzeyi Üzerindeki Bir Hedeften Elektromanyetik Saçılımın Modellenmesi İçin Karma Nümerik Yöntemlerin Geliştirilmesi
(Fen Bilimleri Enstitüsü, 2019)
In electromagnetic wave propagation problems, when there is a target above the Earth’s surface, it is necessary to consider all wave phenomena between the transmitter and the target to model the electromagnetic scattering ...
Eş Akılı Işıma Örüntüsüne Sahip Yansıtıcı Dizi Anten Tasarımı ve Modellenmesi
(Fen Bilimleri Enstitüsü, 2019)
In satellite communication, there are various methods for providing link budget at low elevation angles relative to the horizon line. The most widely used of them is the use of antennas with isoflux radiation pattern. In ...
Metal-Dielektrik İnce Film Optik Filtrelerin Başarımlarının İncelenmesi
(Fen Bilimleri Enstitüsü, 2019)
In this study, the reflection behavior of multilayer thin film optical filter models with special sequences are investigated and effects of material type, material thickness, number of layers, angle of incidence of ...
KD Kanalında Genişbant Haberleşme Teknikleri
(Fen Bilimleri Enstitüsü, 2019)
Because ionosphere allow for the signals to propagate through long distances,
very long-distance communication is possible with relatively cheaper infrast-
ructure. This type of communication allows is realizable between ...
İyonosfer Haritalarının Uzay-Zaman İzgesel Analizi
(Fen Bilimleri Enstitüsü, 2019)
Short Wave (KD), which is in the frequency range of 3-30 MHz, radio wave
propagation is one of the important methods used for long distance
communication. It uses ionosphere and earth to transmit system communication
signal. ...
Ulf-Vlf-Lf Bantları için Alıcı Tasarımı ve Geliştirilmesi
(Fen Bilimleri Enstitüsü, 2019)
ULF-VLF-LF bands are the frequency range of 300 Hz to 300 kHz, where the low frequency signals with long wavelengths that are emitted from artificial or natural sources propagates. Since the signals observed in this frequency ...
