Measurement Method for Determining Electromagnetic Field Attenuation in Nanomaterials Using the TEM Cell (1st Part)
Journal Title: RECENT - Year 2009, Vol 10, Issue 25
Abstract
This paper presents the results of experimental determinations concerning electromagnetic field attenuation in materials containing micro-particles of iron, graphite or carbon black in their structure. In order to determine the shielding effectiveness of electromagnetic absorbents to electromagnetic field, a measuring system based on the TEM cell was proposed and tested. This measurement system was used to determine the electromagnetic shielding properties of materials at frequencies ranging between 1MHz and 1000 MHz. The paper presents both the measuring method and the methodology adopted in order to obtain maximum measurement accuracy. The experimental investigations were conducted in the frame of the CNCSIS project No 429/2006 ”Study of shielding properties of materials obtained by nano-technologies and nano-processing with application in electrical and electronic equipments in order to improve the quality of the environment”.
