Abstract

To perform biomedical Wireless Power Transfer experiments at UHF and microwave frequencies, a need exists for recipes and procedures to construct human tissue mimicking phantoms. This paper outlines the procedure for realizing body-mimicking phantoms and provides some recipes based on demineralized water, sugar (sucrose) and salt (NaCl). Even without using preservatives all samples made for this research maintained the dielectric characteristics for at least ten days when stored at room temperature. A procedure to construct a low-cost RG405 semi-rigid coaxial waveguide-based measurement probe and calibration method are discussed as well. The absolute error in obtained relative permittivity, using this probe, relative to using a Commercially Off The Shelf probe is less than 2.0.
