SAR Calculator | Specific Absorption Rate Tool
By RF Wireless Expert Team
Advertisement
The SAR Calculator estimates the rate at which RF energy is absorbed by biological tissue, expressed in watts per kilogram (W/kg). SAR is a key metric in evaluating human exposure to electromagnetic fields.
EXAMPLE:
-
INPUTS:
- Electric Field = 5 V/m
- Conductiviy of material = 130 S/meter
- Mass Density = 1150 Kg/m^3
-
OUTPUT:
- Specific Absoption Rate (SAR) = 2.826 W/Kg
- Power Density = 0.066
SAR Formula
Benefits/Applications
- Ensures compliance: Helps with safety standards for mobile and wireless devices.
- Protects human health: Predicts energy absorption in tissue models.
- Useful in medical RF applications: Hyperthermia therapy and diagnostics often monitor SAR.
Summary:
Use this calculator to quantify how much RF energy biological tissue absorbs, aiding in safety assessments and compliance with exposure guidelines.
