Abstract
U ovom radu provodi se proračun apsorbirane gustoće snage (Absorbed Power Density APD) u jednostavnom modelu ljudskog tkiva zasnovanom na planarnoj višeslojnoj sredini. Horizontalno iznad promatranog modela, postavljena antena korištena je kao izvor zračenja. Frekvencijsko područje koje se promatralo pri proračunu je : 6 GHz, 10 GHz, 30 GHz i 60 GHz. Kako bi izračunali APD potrebno je odrediti struju duž žice te ozračeno polje što je moguće napraviti na dva načina – analitički i numerički.... More Analiza se provela za slučaj pretpostavljenje sinusne raspodjele struje, te struje dobivene numeričkim proračunom rješavanjem Pocklingtonove integro-diferencijalne jednadžbe primjenom metode rubnih elemenata. Kod proračuna apsorbiranog polja korišteni su Fresnelovi izrazi za koeficijente transmisije i refleksije kojima su obuhvaćena svojstva višeslojnog modela tkiva. Napravljen je proračun APD-a za dvoslojni i troslojni model ljudskog tkiva te su dobiveni rezultati uspoređeni s analitičkim i numeričkim rezultatima dostupnim u relevantnoj literaturi. Less
Abstract (english)
In this paper, the Absorbed Power Density (APD) calculation is performed in a simple human tissue model based on a planar multilayer medium. Horizontally above the observed model, the placed antenna was used as a radiation source. The frequency range observed in the calculation is: 6 GHz, 10 GHz, 30 GHz and 60 GHz. In order to calculate the APD, it is necessary to determine the current along the wire and the irradiated field, which can be done in two ways - analytically and numerically.... More The analysis was performed for the case of assuming a sinusoidal current distribution, and the current obtained by numerical calculation by solving the Pocklington integrodifferential equation using the boundary element method. In the calculation of the absorbed field, Fresnel expressions were used for the transmission and reflection coefficients, which included the properties of the multilayer tissue model. The calculation of APD for two-layer and three-layer model of human tissue was made and the obtained results were compared with analytical and numerical results available in the relevant literature.
