The Investigation of Specific Absorption Rate of Microwaves in the Range of Mobile and Radar Devices by Young and Mature Mice

In the paper measurements of the specific absorption rate (SAR [W/kg]) as a parameter equivalent to the level of energy absorbed by living mice have been presented. SAR values of ellipsoidal phantoms having average electrical parameters of all tissues of mice at different ages have been also calculated using the FDTD method. All evaluations have been realized in waveguides at frequency band of 0,8 -1,8 GHz. The value of rms of electric field strength incident to mouse was of 61,4 V/m (power density of 10 W/m² ). The obtained data of SAR of mice at different ages demonstrates that young mice absorb lower energy level as old (mature) animals.
