In this paper, we investigate an electromagnetic noise problem of the FGM type EM wave absorbers for a hollow cylinder. The FGM layer which have nonhomogeneity only though the radius is considered to be multilayered absorption layers in which the material properties are homogeneous inside each layer. Incident electromagnetic wave is also assumed an electromagnetic plane wave. Therefore, the approximate analytical solutions of electromagnetic fields in the FGM layer and scatted electromagnetic fields in outer medium of the absorber are derived based on the method of separation of variables and the eigen mode expansion of cylindrical coordinate system. Numerical calculations are carried out for the FGM type EM wave absorbers composed of epoxy resin matrix and conductive titanium oxide particles. The absorption performances are quantitatively evaluated. The effects of material composition and absorption layer thickness on the absorption characteristics are then discussed. In addition, a possibility of the material design on the FGM type cylindrical absorber suitable for the absorption of EM wave and heat dissipation is suggested.","subitem_description_type":"Other"}]},"item_16_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"62660","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TAKAHASHI, Satoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"62661","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SUGANO, Yoshihiro"}]}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本機械学会"}]},"item_16_relation_26":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1299/kikaia.77.170","subitem_relation_type_select":"DOI"}}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 2011 一般社団法人 日本機械学会"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1884-8338","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"石巻専修大学理工学部"},{"subitem_text_value":"岩手大学工学部"}]},"item_16_version_type_27":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"高橋, 智"}],"nameIdentifiers":[{"nameIdentifier":"62658","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"菅野, 良弘"}],"nameIdentifiers":[{"nameIdentifier":"62659","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_login","displaytype":"detail","filename":"tjsmea-v77n773p170-180.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"tjsmea-v77n773p170-180","url":"https://iwate-u.repo.nii.ac.jp/record/10103/files/tjsmea-v77n773p170-180.pdf"},"version_id":"d0b2731a-8375-4dd8-9b21-f09a8c3aad83"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Functionally Graded Material","subitem_subject_scheme":"Other"},{"subitem_subject":"Electromagnetic Wave Absorber","subitem_subject_scheme":"Other"},{"subitem_subject":"Analytical Model","subitem_subject_scheme":"Other"},{"subitem_subject":"Analytical Solution","subitem_subject_scheme":"Other"},{"subitem_subject":"Material Design","subitem_subject_scheme":"Other"},{"subitem_subject":"Electromagnetic Property","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"傾斜組成制御した円筒電磁波吸収体の吸収特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"傾斜組成制御した円筒電磁波吸収体の吸収特性"}]},"item_type_id":"16","owner":"3","path":["1519"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-11-17"},"publish_date":"2011-11-17","publish_status":"0","recid":"10103","relation_version_is_last":true,"title":["傾斜組成制御した円筒電磁波吸収体の吸収特性"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-12-19T03:20:24.598450+00:00"}
