Excessive exposure to radiation has an adverse impact on human health, as an increase in
body temperature may damage human organs or tissues, including the brain, eyes, and
skin. Hence, this study assessed the effect of overexposure of radiation on the human head
by analysing specific absorption rate (SAR) and reduction of SAR through the use of novel
metamaterial (MTM). The SAR reduction was performed for GSM 900 MHz and 1800 MHz
bands. A high-frequency electromagnetic simulator was employed throughout this study …
