Abstract

The effect of sheet- and film-type electromagnetic noise suppressors on differential mode (DM) and common mode (CM) transmission characteristics in two parallel lines was investigated. Simple two parallel microstrip lines with a Co-Zr-Nb film were used as a test bench. The transmission characteristics of DM and CM were measured by four-port network analyzer. The ferromagnetic resonance (FMR) and eddy current losses generated in the Co-Zr-Nb film were calculated by 3D full wave simulator, and the effects of these losses on the transmission characteristics were estimated. The results show that the transmission characteristics are different in DM and CM because the frequency characteristics of the losses are different according to the different FMR frequency in each mode. Furthermore, the feasibility of the application of the magnetic film as a frequency-selective CM filter is demonstrated by using the difference in frequency characteristics of loss of DM and CM.

Co-Zr-Nb薄膜并联两导体微带线差分和共模传输特性的评价

研究了片状和薄膜型电磁噪声抑制器对两根平行线差模(DM)和共模(CM)传输特性的影响。采用Co-Zr-Nb薄膜的简单的两条平行微带线作为试验台。采用四口网络分析仪测量DM和CM的传输特性。利用三维全波模拟器计算了Co-Zr-Nb薄膜中产生的铁磁共振(FMR)和涡流损耗，并估计了这些损耗对传输特性的影响。结果表明，由于各模式下FMR频率的不同，损耗的频率特性也不同，DM和CM的传输特性不同。此外，利用DM和CM损耗的频率特性差异，证明了磁膜作为频率选择CM滤波器的可行性。
