Abstract :
In radio frequency (RF) fields, the applications of the loss generation of ferromagnetic thin films are one of good countermeasure for the suppression of electromagnetic (EM) noise emission on transmission line. In this study, to reduce the eddy current loss due to the separation magnetic materials by carbon nanotube, we evaluated the RF EM noise suppression using the sheet typed Fe filled in carbon nanotube (CNT) and epoxy composite sheet on the coplanar transmission line in comparison with that of ferrite film.
