Estimation of Human Body Shadowing for Indoor Propagation in the 5G Frequency Band Using Parallel FDTD Analysis

This study focuses on the human body shadowing the propagation characteristics of local-5G frequency bands in indoor environments. We modeled an indoor propagation environment assuming a conference room containing human bodies and evaluated the propagation characteristics through a large-scale 3D numerical analysis based on the FDTD method. The electric field distribution in the conference room environment excited by the 4.7GHz transmitting antenna, which is used as the local-5G frequency, was calculated, and the propagation characteristics with and without the human bodies were compared. Shadowing and scattering effects due to multiple human bodies in standing and sitting postures were evaluated in the simulations.
