The parameters of the model are estimated from the characteristic admittance and the wave deformation of the rails in z-domain using Padé approximation. We have compared our computed results expressing the proposed model and the conventional π-equivalent circuit model with the corresponding the measurements in on-site tests.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePDFファイルサイズ：\u003c\/strong\u003e812Kバイト\u003c\/p\u003e","brand":"IEEJ-PDF","offers":[{"title":"PDFダウンロード（一般価格440円\/会員価格220円） \/ A4 \/ 4","offer_id":47682007171311,"sku":"IEEJ-BTB2025069-PDF","price":440.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-PDF_bumontaikai_01ba6081-499f-4834-aed5-8628c69b8889.png?v=1770872736","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-btb2025069","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
