Specific Absorption Rate (SAR) Calculator
This calculator determines the Specific Absorption Rate (SAR), which measures the rate at which the body absorbs energy from an electromagnetic field. It's primarily used to evaluate radiation exposure from devices like mobile phones.

SAR Calculation Formula
Where:
- $$σ$$ = electrical conductivity of the tissue (S/m)
- $$ErmsE_{\text{rms}}Erms$$ = root mean square electric field (V/m)
- $$ρ\rhoρ$$ = mass density of the tissue (kg/m³)
- $$SAR$$ = Specific Absorption Rate (W/kg)
Specific Absorption Rate (SAR) quantifies how much electromagnetic energy is absorbed by human tissue, particularly in relation to devices like cell phones and wearables. Regulatory bodies like the FCC and ICNIRP set SAR limits to ensure safe exposure. This calculator uses input values such as conductivity, electric field strength, and tissue density to compute SAR and assess compliance with safety guidelines.
