Abstract

The expanding use of electric devices in everyday life has led to an augmented interest in investigating the interaction between electromagnetic fields and biological tissues. In order to ensure the secure advancement of electromagnetic devices and avoid potential health hazards, comprehending the distribution of electromagnetic fields in the human body is imperative. Magnetic resonance imaging (MRI) is a widely accepted technique for medical diagnosis. The use of high-field MRI has become increasingly popular in recent years as it can enhance signal-to-noise ratio (SNR) and image resolution, thereby decreasing acquisition time. This paper aims to investigate the impact of electromagnetic waves on the human body, particularly the specific absorption rate (SAR). Accurately calculating SAR in humans poses significant challenges and requires advanced mathematical models and computer simulations. To this end, the study utilized the Microwave Studio Transient Solver available in CST Studio Suite 2020 to solve the electromagnetic problem in different human models.
