SAR Reduction in Human Head Phantom Using Nanomaterial MIMO Antenna
By
Progress In Electromagnetics Research Letters, Vol. 108, 103-112, 2023
Abstract
This work aims for nonionizing radiation assessment to reduce Specific Absorption Rate (SAR) in the IEEE SAM phantom using MIMO antenna. The traditional copper material MIMO is designed with mode characteristics and validated for 2.4 GHz in this experiment. The MIMO antenna, when placed near SAM phantom and SAR, is estimated. Copper-based antennas are replaced by nanomaterial-based antennas, such as graphene, multi-walled carbon nanotube (MWCNT), and single walled carbon nanotube (SWCNT), to study SAR behavior. SAR is reduced using Nanomaterial based antenna in which SWCNT significantly reduces SAR up to 66 percent using Altair's Feldberechnung für Körper mit beliebiger Oberfläche (FEKO).
