COMPUTATION OF SAR INSIDE EYEBALL FOR 1.5-GHZ MICROWAVE EXPOSURE USING FINITE-DIFFERENCE TIME-DOMAIN TECHNIQUE

From the standpoint of studying the biological effects of microwaves o n human eyes, this paper numerically examines the specific absorption rate (SAR) inside the eyeball, using the finite-difference time-domain (FD-TD) method, which does not require very much computer storage. Tw o kinds of highly heterogeneous models constructed by us and Taflove's group are used to compute the SARs inside the eyeball for 1.5-GHz mic rowave exposure under the 1991 ANSI protection guideline. The SAR cont our lines and the spatial distribution are shown inside the eyeball. C omparison is also made between the SARs for the two computation models .
