Efficient evaluation of specific absorption rate for MIMO terminals [PDF]

Electronics Letters, 2014
Multi‐antenna‐enabled terminal devices are required to comply with the standards for limiting human exposure to electric fields. However, when compared to the traditional single‐antenna terminals, a comprehensive evaluation of specific absorption rate (SAR) for multi‐antenna terminals is impractical.
