Tissue equivalent material for hand phantoms.
We suggest that to best reproduce the interaction between a handheld wireless transceiver and the hand holding it, the dielectric properties of the hand phantom should be similar to those of the palm of the hand. The proposed target permittivity and conductivity values are presented and tabulated at a number of frequencies of interest. We have developed suitable phantom hand materials based on carbon-loaded silicones and demonstrated that it was possible to match the proposed dielectric properties in the frequency range 600-6000 MHz.
