Near-Field Shielding Effect of Oval Human Model for Dipole Antenna Using High-Loss Dielectric and Magnetic Materials

摘要

In this study, the shielding effect of high-loss dielectric and magnetic materials themselves and also an oval human model placed behind these material, were investigated by the FDTD method, for near-and far-field exposure, using the half-wave length dipole antenna. According to the results, a high- loss magnetic material showed a large shielding effect (average 20dB) compared to the high-loss dielectric material, for near- and far-field shields.
