Specific Absorption Rate (SAR) is a crucial measure in fields like telecommunications and healthcare. Understanding SAR helps in ensuring safety and compliance with international guidelines. This article introduces a SAR calculator, a tool designed to help professionals calculate SAR easily and efficiently.
Definition
The Specific Absorption Rate (SAR) calculator falls under the category of scientific calculators. It's used to calculate the energy absorbed by body tissues when exposed to a radio frequency (RF) electromagnetic field. The calculator simplifies this complex calculation, making it accessible to researchers, engineers, and students.
Detailed Explanations of the Calculator's Working
The SAR calculator uses input parameters like the constant depending on the tissue type, electric field strength, mass of the tissue, and exposure time. It then employs the mathematical formula specific to SAR to compute the absorbed energy rate. The design is modern, and its interactive interface ensures a seamless user experience.
Properly Formatted Formula with Variables Description
The SAR calculation formula used in the calculator is: = C*E^2/m*t
Where:
- C: Constant depending on tissue type (W/kg)
- E: Electric field strength (V/m)
- m: Mass of the tissue (kg)
- t: Exposure time (seconds)
Example
For instance, using the SAR calculator with C=1.5 W/kg=1.5W/kg, E=50 V/m, m=2kg, and t=1 s=1s, the SAR would be 1875.00W/kg
Applications
Medical Imaging
The SAR calculator is vital in medical imaging to ensure that the energy absorbed by patients stays within safe limits.
Mobile Communications
It's also applied in mobile communications to measure the absorption rate of RF energy by human tissues.
