Bu makalede, insan vücudu içerisinde Terahertz (THz) elektromanyetik dalgalarının yayılımı
araştırılmış ve alveolar boşlukları ve insan dokuları içindeki Nano Ölçekli Vücut Merkezli Kablosuz
Ağların sistem performansının bir modeli tartışılmıştır. THz frekans bandı kablosuz iletişimde, özellikle
nano ölçekli kablosuz iletişimde yeni uygulamalar sağlamaktadır. Bu makalede geliştirilen model, THz
bandının kablosuz iletişimi için nano ölçek ortamında Alveoların boşluklarında ve insan dokularından
yayılan EM dalgalarının toplam emilim kaybı, yol kaybı ve kapasite özelliklerini hesaplamaktadır.
Gürültü seviyesi ve yol kayıplarının modellenmesine dayanarak, kanal kapasitesi de hesaplanmıştır.
Sonuç olarak, Kablosuz Nano Telsiz Duyarga Ağlarının, insan vücudu üzerinden iletişim kurabildiği
gösterilmektedir. Modelin sayısal analizine göre 3 iletim penceresi olan ω1 = [0.01 THz - 0.5 THz], ω2 =
[0.58 THz - 0.74 THz] ve ω3 = [0.77 THz - 0.96 THz] bulunmuştur. Kablosuz Ağların THz iletişimde en
uzun ve düşük geçiş penceresi olan olan 0.01 THz - 0.5 THz aralığı akçigerlerde ve kan için Nano
Ölçekli Vücut Merkezli Kablosuz Ağlar evrensel nano düğüm tasarlayabilmek için modellenmiştir.

NUMERICAL ANALYSIS OF THE ALVEOLAR SPACES AND HUMAN TISSUES FOR NANOSCALE BODY-CENTRIC WIRELESS NETWORKS

This paper investigates the propagation of Terahertz (THz) electromagnetic waves inside the
human body and discusses a model of the system performance of Nanoscale Body-Centric Wireless
Networks inside the alveolar spaces and human tissues. THz band wireless communication enables new
applications especially in nanoscale wireless communication. The model developed in this paper
calculates the total absorption loss, path loss and capacity properties of EM waves propagating through
the Alveolar Spaces and Human Tissues in nanoscale environment for THz band wireless
communication. Based on the modeling of noise level and path losses, the channel capacity is calculated.
The results show that Wireless Nanosensor Networks (WNSNs) can communicate through the human
body. According to the numerical analysis of the model several transmission windows which are ω1 =
[0.01 THz – 0.5 THz],          ω2 = [0.58 THz – 0.74 THz] and ω3 = [0.77 THz – 0.96 THz] have been found
for Nanoscale Body-Centric Wireless Networks. The longest and lowest transmission window which is in
the range of 0.01 THz – 0.5 THz values have been analyzed for blood, plasma, RCBs and water to design
universal nanonode for Nanoscale Body-Centric Wireless Networks at gases in lungs and blood.
