Effects of Human Body on Characteristics of a Reverberation Chamber for Microwave Frequencies

In this paper, several posture models is set up in the reverberation chamber, and the effects of human body on the electric field distribution is quantitatively evaluated by numerical simulation at 2.45 GHz. Specifically, 12 observation points are set up, and the simulation is performed by changing posture models and stirrer angles. The simulation results show that the electric field amplitude becomes less than 1/100 and the electric field uniformity deteriorates with posture models. Also, the results of the analysis of variance show that the influence of the observation points is smaller compared to the previous study simulated at 403.5 MHz. Furthermore, it is found out that the electric field uniformity deteriorates as the number of observation points increased. Future studies includes evaluating the effects of various postures and comparing them with actual measurements.
