bounce)による電磁放射ピークの周波数は，電源グラウンド層間入力インピーダンス（以下，PCBインピーダンスと呼ぶ）の周波数特性から予測可能とされているが，その対応関係には不明の部分が多い．本論文では，PCBの電磁放射とPCBインピーダンスの周波数スペクトルをFDTD (Finite-Difference Time-Domain)法で解析し，実測値との対照から両者の対応機構を考察した．その結果，PCBインピーダンスの大きさに比して十分小さい内部抵抗の電圧源でPCBを励振すれば，電磁放射のピークはPCBインピーダンスが極小となる周波数で現れるが，それは内部抵抗の増大とともにPCBインピーダンスが極大となる周波数へ移行することがわかった．また，PCBインピーダンスが極大，極小となる二つの周波数（共振周波数）における抵抗成分（以下，共振抵抗と呼ぶ）から求めた放射電力比は二乗放射電界比とおおむね一致すること，それゆえにPCBの放射ピーク周波数は励振源の内部抵抗とPCBインピーダンスの共振抵抗の両者で決まること，などが明らかとなった．","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"573","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Fujiwara,
