Abstract

The article discusses the physical nature of the optimum sheet resistance for the integrated electromagnetic noise suppressor. The system is a microstrip-line with Co-Al-O granular soft magnetic film on top of the signal line. Experimental result shows that there is an optimum sheet resistance which maximize the loss generation at the magnetic materials portion. Loss generation can be maximized by combining maximum eddy current losses and FMR losses.
