Numerical study of electromagnetic
interaction between an adjacent antenna and a human
head model requires long computation time and large
computer memory. In this paper, two speeding up
techniques for a dispersive algorithm based on finitedifference
time-domain method are used to reduce the
required computation time and computer memory. In
order to evaluate the validity of these two speeding
up techniques, specific absorption rate (SAR) and
temperature rise distributions in a dispersive human head
model due to radiation from an antenna integrated into a
pair of smart glasses are investigated. The antenna
integrated into the pair of smart glasses have wireless
connectivity at 2.4 GHz and 5th generation (5G) cellular
connectivity at 4.9 GHz. Two different positions for
the antenna integrated into the frame are considered in
this investigation. These techniques provide remarkable
reduction in computation time and computer memory.
