Abstract	In this paper, we discuss the shielding effects of lossy dielectric materials located in front of the human body. Using the Method of Moment, we investigate the shielding effects by calculating the `whole average SAR' and `local SAR' for a three layered elliptical model of the human body, which simulated the skin, fat and muscle tissues. Two dielectric shield constants at a high frequency range of 1.3 GHz are selected for the shielding investigation and the results are presented for several thickness and gap values (between the human model and shield). This paper presents an interesting viewpoint on the high frequency shielding properties of these materials, and implementations for protecting the human body from possibly damaging electromagnetic effects.
