The transfer functions of the low- and high-density polyethylene films in the PEA system are obtained based on the viscoelastic theory, which allow us to directly calculate acoustic attenuations in the polyethylene films. The calculated acoustic waveforms passed through the polyethylene films show good agreement with the measurements. By using this method, theoretical space charge profiles in the low- and high-density polyethylene films before a charge injection are obtained. This technique is useful for a calibration of the PEA system at the initial condition.本誌: 電気学会論文誌A（基礎・材料・共通部門誌） Vol.141 No.10 （2021） 特集：9th International Symposium on Electrical Insulating Materials本誌掲載ページ: 527-532 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejfms/141/10/141_527/_article/-char/ja/
