Sohn, Jaecheon Han, S. H. Yamaguchi, M. Lim, S. H. 2024-01-21T01:31:50Z 2024-01-21T01:31:50Z 2021-09-04 2007-03 0304-8853 https://pubs.kist.re.kr/handle/201004/134619 Integrated-type electromagnetic noise suppressors, based on a coplanar wave-guide transmission line, are investigated, incorporated with a SiO2 dielectric and a nanogranular Co- Fe-Al-O magnetic thin film. The length of the magnetic thin. lm is varied from 2 to 15 mm, while its thickness and width are fixed at 1 and 50 mm, respectively. In the measurement frequency range of 0.1-20 GHz, no obvious resonance is seen at the shortest length of the magnetic thin. lm, but resonance behavior occurs at larger length. A very clear resonance occurs at the largest length of 15 mm, where the resonance frequency is similar to 10GHz and the signal attenuation is as large as -20 dB. The observed resonance frequency is much higher than the ferromagnetic resonance frequency and the main mechanism of loss generation is found to be L-C resonance. (C) 2006 Elsevier B. V.
