Testing the Effect of H-field Using Biological Phantom

The purpose of this paper is to propose a method to test the biological phantom after an exposure of the electromagnetic field (H-field). The phantom is believed to be influenced by the H-field created by wireless power transfer procedure. In the investigation, the phantom has been exposed for about 150 min. Two parameters were measured from the phantoms which are the impedance and the temperature before and after the exposure of the H-field. From the outcome, we can identify whether there are any changes detected in the assigned frequency. Both parameters change when exposed in the H-field but there are no significant changes after a duration of time exposed in the H-field zone indicates this range of frequency is safe to be used upon the biological phantom. This biological phantom comprises of the cucumber, saline and corn oil. In this test, it is utilizing 20% of corn oil and 80% of saline inside the cucumber as to show the arrangement of fat in typical human body. Since the changes is very low, this WPT setup is safe for testing the biological tissues. Nevertheless, as the complexity of the biological tissues, there are still many aspects to be considered and highlighted as this study play an important role to be referred for the next study about the effect of H-field towards the biological phantom.
