Effect of Incidence Angle on the Spatial-Average of Incident Power Density Definition to Correlate Skin Temperature Rise for Millimeter Wave Exposures

This article reports on an intercomparison study the effect of incidence angle spatial average incident power density (PD) and resultant temperature rise using computational thermographic measurement approaches. Two definitions PD—the peak spatial-average normal component Poynting vector norm vector—were compared. First, PD in a layered skin model was conducted for 4 × dipole array antenna. The variations caused by antenna type, antenna-body distance, to these were then discussed. results revealed that both are good agreement correlate with small or moderate angles. heating factor enhanced transverse-magnetic-like polarized waves large-angle incidences because Brewster effect. scenario confirmed be essential considering rise.
