    Design and Analysis of a Metamaterial Absorber for Applicaion at 3.5GHz
    (International Islamic University Chittagong, 2024-06) Hossain, Syed Mustavi
    Analysis of a metamaterial absorber with an S-shaped structure is suggested to reduce the specific absorption rate (SAR) at 3.5 GHz. This absorber exhibits single negative metamaterial characteristics and achieves an absorption rate of over 90% for all electromagnetic polarization angles. In the age of 5G, numerous applications are functioning at various frequency ranges, emitting substantial amounts of electromagnetic energy (EM) that possess an elevated SAR value. This radiation has an impact on the human body, specif ically the head and hands, which are exposed to it. In Malaysia, a frequency band of 3.5 GHz has been designated for 5G communication. However, this has resulted in the emission of undesirable signals due to high Specific Absorption Rate (SAR) values. To address this issue, a proposed absorber would be implemented to reduce SAR levels.
