Enes -
I have made these two graphs, one for conductivity and one graph for permittivity so that all data is clearly visible. Excel File

-As you will surely notice that a third frequency range for the sugar-based solution was not possible because the conductivity was above required value, while we tried to maintain the required permittivity level.

-The agar-gel based medium seems to represent both the aimed and the already existing solution fairly well in the whole frequency range, prior and also after boiling.  The problem that lies with agar is that for this concentration of 15g / 100ml Water, it will be hard to place it into the dummy due to the consistency of the gel, before it is even boiled the mixture is a toothpaste like mixture, it does not flow really well...we will try to reduce it where it would be able to flow nicely into and perhaps out of the dummy.  If not, the question remains of how close could we come so that filling the dummy would not be a problem.

-Also to conclude, the problem with MegaWave's solution did not lie in the conductivity but rather the permittivity.

-The existing solution table which is also in this worksheet, comes from the following source:
Estimation of Body-Tissue Simulating liquid (http://www.emc-center.jp/index.html.en)

-The precise gel medium which we have a recipe for, that is not attached to this e-mail is also graphed with the rest in these two graphs.  The major problem with this is the cost of it. approx 3500 would be needed to fill the dummy, and it would be filled a portion at a time.

Further work will continue with MegaWave's automated antenna test system.
