Abstract :
A concept to integrate a thin-film radio-frequency noise suppressor in a transmission line is demonstrated by using Co85Nb12Zr3 amorphous film with the microwire array structure. The ferromagnetic resonance loss generation at high frequencies is essential to realize this idea. The degree of noise suppression is only less than 1 dB, which should be improved by optimum design to integrate the magnetic film.
