چکیده
|
The present article is a theoretical contribution to the comparative study of a single layer electromagnetic shielding efficiency of high density polyethylene/trioxide of vanadium (hdpe/v2o3) and low density polyethylene/trioxide of vanadium (ldpe/v2o3) conductive polymers composites in near and far field. this study was realized over a wide range of frequency (50mhz-50ghz). to this effect,the volume fraction of the conductive inclusions is fixed. this volume fraction leads an electrical conductivity which verifies the condition of a good conductor (σ/ωε0≫1).the thickness of the shield was chosen superior to the depth of penetration of the electromagnetic wave. in these conditions the multi-reflections are neglected.
