Description
本発明の効果を確認するため、３次元の電磁界シミュレータを用いてシミュレーションを行った。信号線４の一端には１Ｗの電力を入力し、信号線４の他端は７５Ωの終端抵抗で終端することとして、電磁干渉抑制体３の面内方向における実効的な誘電率を変えつつ、３ｍ遠方における放射ノイズ（電界）を計算した。その上で、電磁干渉抑制体３を貼付しない場合との差分の周波数に対する変化をグラフにプロットした。即ち、電磁干渉抑制体３を貼付しない場合に発生していた輻射ノイズと全く同じレベルの輻射ノイズが発生していた場合には、０ｄＢ μＶとなる。結果としてのグラフを図２に示す。 In order to confirm the effect of the present invention, a simulation was performed using a three-dimensional electromagnetic field simulator. While changing the effective dielectric constant in the in-plane direction of the electromagnetic interference suppressor 3, 1 W of electric power is input to one end of the signal line 4 and the other end of the signal line 4 is terminated with a termination resistor of 75Ω. Radiation noise (electric field) at a distance of 3 m was calculated. Then, the change with respect to the frequency of the difference with the case where the electromagnetic interference suppression body 3 is not affixed was plotted on the graph. That is, when radiation noise having the same level as that generated when the electromagnetic interference suppressing body 3 is not attached is 0 dB μV . The resulting graph is shown in FIG.
