For investigating the validity of the two exclusion criteria in the ANSI safety guide revised in 1982, this paper examines numerically the specific absorption rate (SAR) in the lossy sphere simulating a human head exposed to the microwave near-fields due to a half wavelength dipole antenna. The SAR patterns on the spherical surface are calculated with respect to the antenna input powers and the frequencies.

For studying the harmful influences of a portable transmitter on the human eyeball, this letter examines numerically the specific absorption rate (SAR) using the sphere model exposed to the near-fields of a half-wavelength dipole antenna. The SAR's inside the eyeball due to the 1.5 GHz near-field exposure are calculated in relation to the antenna location.
