How accurate is 3 phantom model used in dipoleSAR example..

Also How to calculate SAR for a given frequency??

I have tried with sinusexcite and not getting desired results.. Tried with other software and results are not matching(more than 1.5W/Kg difference!)..

Is it my fault or using 3 phantom model?

What is a 3 phantom model?

Have you looked at the tutorials covering SAR?

You should not use sinusexcite. It takes longer and is difficult to determine convergence.

1.5W/kg difference does not say anything....

Yes, I have modified the dipole_SAR.m file and changed it to my antenna. 3 phantom model is the model with skin, headbone and brain.

I have an antenna with SAR at a given frequency(2GHz) with given power, So I need to calculate the SAR at that frequency. Can we measure SAR of an antenna for specific power? (How to normalize the power to 0.25W, default is 1W..)
