The stack for the electromagnetic noise filters consists of the nano-granular (Co41Fe38Al13O8) soft magnetic film2/transmission linelayer (Cu/Ti)2-substrate. A good signal-attenuation feature along with a low signal-reflection feature is observed in the present filters. Especially in the noise filter incorporated with a Co41Fe38Al13O8 magnetic film with lateral dimensions of 2000 mm wide, 15 mm long and 1 mm thick, the maximum magnitude of signal attenuation reaches -55 dB, and the magnitude of signal reflection is below -10 dB in the overall frequency range. And this level of signal attenuation is much larger than that of a noise filter incorporated with a Fe magnetic film. 한국자기학회 RF Integrated Electromagnetic-Noise Filters Incorporated with Nano-granular Co41Fe38Al3O8 Soft Manetic Thin Films on Coplanar Transmission Line Article 2 Journal of Magnetics, v.10, no.4, pp.163 - 170 Journal of Magnetics 10 4 163 170 kci ART000981854 nanogranular soft magnetic film electromagnetic noise filter low pass filter L-C resonance ferromagnetic resonance nanogranular soft magnetic film electromagnetic noise filter low pass filter L-C resonance ferromagnetic resonance
