“…There is liquid, gel, semisolid and solid materials. Most of reported human body phantom materials are using gel and semisolid [2][3][4][5][6][7]. Phantom of solid material using agar-based is studied in [2] to operate from 0.9 GHz to 10.0 GHz.…”

This research is intending to investigate the human skin phantom's dielectric constant. The phantom will be used to test the electromagnetic compatibility later on since it can be harmful if it is directly tested on real human body. The human body phantom is made to have similar property as a skin tissue, at the operating frequency of 2.4 GHz. A methodology of the process is discussed. The phantom is fabricated, tested and measured. A fabricated phantom with the desired permittivity of εr and conductivity of σ values; are controlled by the amount of polyethylene powder and sodium chloride. The information on dielectric constant of the phantom based on measured values of εr and σ will be determined. The factors in making a good phantom is discussed. A good level of agreement is observed between simulation and measurement results.

When power is to be transferred to a mm-sized \gls{imd}, located multiple cm deep inside the human body, the main goal is often to maximize the received power, within the applicable \gls{sar} limits. It has been shown that, for equivalent homogeneous biological tissue, there is little difference between the received power using \gls{wpt} at (sub-)GHz frequencies compared to low MHz frequencies. However, it remains unclear whether the introduction of additional tissue layers, thus more accurately approximating the real environment, changes the optimal frequency for maximum received power. This paper presents an analytical model that can be used to calculate the \gls{em} fields, \gls{sar}, received power, and \gls{pte} in a planarly layered environment, consisting of an arbitrary number of layers with arbitrary thicknesses and arbitrary dielectric properties. The model is first validated by comparing it to CST Studio Suite\textregistered. It is then used to determine the optimal frequency for \gls{wpt} to a mm-sized implant, located multiple cm deep inside the human body. The optimal frequency is 10 kHz, and the received power is approximately constant up to 300 kHz. The same holds for the \gls{pte}.
