Single Human Body and Human Crowds RCS

In the recent years, due to the integration of electronic devices into everyday life there is an increasing public concern about the impact of electromagnetic wave on the human body.

Application note is focused to homogenous dielectric and equivalent metallic human body in the frequency range from 2 GHz to 10 GHz. The skin depth is between 2 mm at 10 GHz and 60 mm at 2 GHz. Because of the small skin depth at higher frequencies, the most efficient simulation model of the human body proved to be metal model with losses included in form of distributed loadings. The number of unknowns is greatly reduced , without reducing the accuracy of the simulation.

Simulations include: dielectric model of human body at 2 GHz, metallic model with distributed loadings at 2 and 10 GHz, human crowd with 49 bodies with properly distributed and random positions at 0.9 GHz. Computer configuration used is standard desktop PC with increased RAM and single inexpensive GPU card added for the matrix inversion speed up.
