From the standpoint of studying the biological effects of microwaves on 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. Two 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 microwave exposure under the 1991 ANSI protection guideline. The SAR contour lines and the spatial distribution are shown inside the eyeball. Comparison is also made between the SARs for the two computation models.
