The following formula was used to calculate the Power Density: 30  P  G E2 E (V/m) ＝ Power Density: Pd (W/m²) ＝ d 377 E ＝ Electric field (V/m) P ＝ RF output power (W) G ＝ EUT Antenna numeric gain (numeric) d ＝ Separation distance between radiator and human body (m) The formula can be changed to Pd ＝ 30  P  G 377  d 2 SPORTON INTERNATIONAL INC.
