This paper presents a traceable experimental dosimetry method to measure absorbed power density (APD) from body-mounted wireless devices at frequencies above 10 GHz. It combines a miniaturized broadband probe, a composite skin-equivalent phantom, and reconstruction/calibration procedures, with validation using reference antennas. The approach is reported as validated for 24–30 GHz and extendable to 10–45 GHz, supporting regulatory-type testing aligned with international safety standards.
Impact of Anthropomorphic Shape and Skin Stratification on Absorbed Power Density in mmWaves Exposure Scenarios
This dosimetry study used FDTD simulations at 28 GHz to evaluate how skin stratification and anthropomorphic modeling affect absorbed power density (APD) estimates. APD was higher with stratified skin than with homogeneous skin for a wearable patch antenna (16%–30% higher), while plane-wave differences were smaller (<11%). The authors argue that simplified skin models may underestimate exposure in mmWave wearable scenarios.
