Calculator For SAR

Specific Absorption Rate (SAR) is a measure of the rate of RF (radiofrequency) energy absorption by the body from the source being measured – in this case, a cell phone. SAR provides a straightforward means for measuring the RF exposure characteristics of cell phones to ensure that they are within the safety guidelines set by the FCC.

Specific Absorption Rate (SAR) :

Specific Absorption Rate (SAR) is the unit of measurement for the amount of radio frequency energy absorbed by a body when using a wireless device like Mobile Phones .The SAR Calculator requires you to enter the Electric Field (Volts/m), Conductivity of the Material (Siemens/m) and Mass Density (Kg/m3). It gives the SAR value in W/Kg .Using the following formula :-

Specific Absorption Rate of Mobile Phones :

SAR = ( C * Erms2 ) / D
SAR = Specific Absorption Rate
C = Conductivity of Human Tissue
E = Electric Field (RMS)
D = Density of Human Tissue Fat
