Generally, a polarizer internally decomposes the input electric field into two orthogonal components (fast polarization and slow polarization) and generates a phase difference between those components to produce a polarization different from the input. Therefore, the response of a polarizer is characterized by two parameters: the angle at which the electric field is decomposed and the generated phase difference. In Stokes space, each polarization is represented as a vector, and it is known that a rotation operator represents the response of a polarizer.\nIn this presentation, we propose the new method to determine polarizers' response parameters by converting the input and output polarizations into Stokes vectors to identify the rotation operators from a necessary and sufficient dataset. In the conventional method, the measured electric field components are analyzed in real space, and the equation for determining the response parameters of the polarizer tends to be complicated. However, by considering the polarizer's response geometrically in Stokes space, the response parameters can be determined more prospectively. \nIn order to confirm the analysis method, a polarization measurement were carried out using a horn antenna detector and two polarizers for 110/138 GHz transmission lines. The method to determine the response parameters of one polarizer and to simultaneously determine the response parameters of two polarizers were verified. In both cases, it was confirmed that the output polarizations calculated from the determined response parameters agreed with the measured polarizations with a purity of more than 99%.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"Korea-Japan Workshop on Physics and Technology of Heating and Current Drive","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Satoru, Yajima"}],"nameIdentifiers":[{"nameIdentifier":"942138","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takayuki, Kobayashi"}],"nameIdentifiers":[{"nameIdentifier":"942139","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shinichi, Hiranai"}],"nameIdentifiers":[{"nameIdentifier":"942140","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jun, Hinata"}],"nameIdentifiers":[{"nameIdentifier":"942141","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ken, Kajiwara"}],"nameIdentifiers":[{"nameIdentifier":"942142","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ryosuke, Ikeda"}],"nameIdentifiers":[{"nameIdentifier":"942143","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahiro, Shinya"}],"nameIdentifiers":[{"nameIdentifier":"942144","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hibiki, Yamazaki"}],"nameIdentifiers":[{"nameIdentifier":"942145","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koji, Takahashi"}],"nameIdentifiers":[{"nameIdentifier":"942146","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Satoru, Yajima","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"942147","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takayuki, Kobayashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"942148","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shinichi, Hiranai","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"942149","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jun, Hinata","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"942150","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ken, Kajiwara","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"942151","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ryosuke, Ikeda","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"942152","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahiro, Shinya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"942153","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hibiki, Yamazaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"942154","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koji, Takahashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"942155","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Development of a Characterization Method for Polarizers Focusing on Polarization Representation in Stokes Space","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of a Characterization Method for Polarizers Focusing on Polarization Representation in Stokes Space"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-03-02"},"publish_date":"2021-03-02","publish_status":"0","recid":"82540","relation_version_is_last":true,"title":["Development of a Characterization Method for Polarizers Focusing on Polarization Representation in Stokes Space"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:20:36.740858+00:00"}
