WEMA26: RF Digital Twins with Human Bodies: A Hybrid EM Simulation Approach

Presentation Abstract
Achieving reliable wireless connectivity on the human body presents significant challenges due to radiation hazards, antenna design, and OTA measurements. This work demonstrates the use of the FDTD method to create near-field Huygens boxes that incorporate MCAD models, PCB designs with circuits, and surface mesh of a human body. For larger environments, these near-field Huygens boxes are integrated into 3D ray-tracing to evaluate environmental effects, including human presence for blockage. The hybrid approach is correlated, accounts for multipath effects for GNSS and indoor, and delivers significant runtime savings, providing a comprehensive RF digital twin solution for RF test and measurement.
