Abstract
A complete test system comprising assembled hardware and custom-built software was developed for investigating whether RFID radiation produces significant effects in biologics. Furthermore, we document a method for determining specific absorption rate (S.A.R.) using vials containing 1.5 cc of saline to represent biological samples. This methodology yielded S.A.R. values of approximately 30 W kg−1–150 W kg−1 for 915 MHz and 320 W kg−1–450 W kg−1 for 2.45 GHz. Finally, the key system components – the transverse electromagnetic (TEM) cell, vial, and saline solution – were modelled using a FDTD software. Through modelling, we obtained values for the absorption as a percentage of the incident power – 0.2% for 915 MHz and 7.32% for 2.45 GHz. These values approximately matched those calculated – 0.36% for 915 MHz and 5.0% for 2.45 GHz.
