Exploring the Impact of High-Frequency Electromagnetic Fields in Railway Compartment: A CST Studio Suite Simulation Study

The influence of radiofrequency (RF) electromagnetic fields (EMF) on human occupants within shielded regions of railway compartment is being investigated in this study using the CST Studio Suite program. The simulations investigate the specific absorption rate (SAR) for 1 gram and 10 grams of human tissue in nine carefully selected settings, with a focus on a Planar Inverted-F Antenna (PIFA) operating at 1800 MHz. Within the limited space of the railway wagon compartment, these positions symbolize various spots of the possible human body occurrence. With the 1g method, the highest simulated SAR value was 2.41 W/kg, while with the 10g method, it was 0.98 W/kg.
