SAR Calculator
Use this tool to calculate the Specific Absorption Rate (SAR) and power density based on the electric field, conductivity, and mass density of a material.
Specific Absorption Rate (SAR): 0 W/kg
Incident Power Density: 0 W/m²
Formula:
- Specific Absorption Rate (SAR) = (σ × E²) / md
- Incident Power Density = E² / 377
Where:
- σ = Conductivity of Material (S/m)
- E = Electric Field (RMS) (V/m)
- md = Mass Density (kg/m³)
- 377 = Impedance of free space (Ω)
This tool helps with:
Estimating RF energy absorption in compliance with SAR regulations.
Evaluating exposure levels of wireless devices based on field strength.
Calculating incident power density from measured electric fields.
