Sobre IBD

Niniejsza praca badawcza ma na celu przedstawienie opartej na symulacji oceny rozkładu SAR w tkankach ludzkiego ucha poddanych promieniowaniu o częstotliwości radiowej (RF) z telefonów komórkowych. Przedstawiono uproszczony trójwarstwowy model anatomiczny skóry, podskórnej tkanki tłuszczowej i małżowiny usznej. Parametry elektryczne i termiczne każdej warstwy, takie jak przewodność, przenikalność względna, gęstość i ciepło właściwe, zostały uwzględnione w modelu obliczeniowym. Metoda różnic skończonych w dziedzinie czasu (FDTD) została użyta do symulacji propagacji fal elektromagnetycznych w strukturze tkanki oraz do analizy rozkładu przestrzennego pola elektrycznego i magnetycznego. Wartości SAR obliczono dla częstotliwości stosowanych w komunikacji mobilnej, tj. 900 MHz, 1800 MHz i 2400 MHz. Zbadano również wpływ kontrastów dielektrycznych w warstwach tkanek na głębokość wnikania i wzorce osadzania energii.
