Above 3GHz, however, this conventional calibration has the possibility of inaccurate assessment because the diameter of the probe is comparable with the cross-sectional dimension of the waveguide. Therefore, an alternative calibration for the SAR probe based on another principle is required and is developed by the authors. In our proposed calibration, first, the gain of the reference antenna in the liquid is evaluated by use of two antenna method based on the Friis transmission formula in the conducting medium, and then the electric field radiated by the reference antenna is related to the output voltage of the SAR probe at a point in the liquid. However, the fields are significantly reduced in the liquid and the gain is impossible to be calibrated in the far-field region. To overcome this difficulty, the Friis transmission formula in the conducting medium is extended in the near-field region. In the paper some numerical and experimental results of estimated gain based on the Friis transmission formula in the near-field region are reported and the validity of the new formula is checked.", "subitem_description_type": "Abstract"}]}, "item_8_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "電子情報通信学会"}]}, "item_8_relation_31": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ap-s.ei.tuat.ac.jp/isapx/", "subitem_relation_type_select": "URI"}}]}, "item_8_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright (C) 2006 IEICE"}, {"subitem_rights": "本文データは学協会の許諾に基づきISAP Archivesから複製したものである"}]}, "item_8_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Akagawa, Takuhei"}], "nameIdentifiers": [{"nameIdentifier": "169014", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ishii, Nozomu"}], "nameIdentifiers": [{"nameIdentifier": "169015", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sato, Ken-ichi"}], "nameIdentifiers": [{"nameIdentifier": "169016", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hamada, Lira"}], "nameIdentifiers": [{"nameIdentifier": "169017", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Watanabe, Soichi"}], "nameIdentifiers": [{"nameIdentifier": "169018", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-26"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "ISAP_2006_2C2b-4.pdf", "filesize": [{"value": "146.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 146100.0, "url": {"label": "ISAP_2006_2C2b-4.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/30946/files/ISAP_2006_2C2b-4.pdf"}, "version_id": "def3e575-5e56-45c2-9b78-9df0240136e3"}]}, "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 paper", "resourceuri": "http://purl.org/coar/resource_type/c_5794"}]}, "item_title": "A Gain Measurement in the Liquid Based on Friis Transmission Formula in the Near-Field Region", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "A Gain Measurement in the Liquid Based on Friis Transmission Formula in the Near-Field Region"}, {"subitem_title": "A Gain Measurement in the Liquid Based on Friis Transmission Formula in the Near-Field Region", "subitem_title_language": "en"}]}, "item_type_id": "8", "owner": "1", "path": ["457", "1822"], "permalink_uri": "http://hdl.handle.net/10191/25753", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-02-25"}, "publish_date": "2014-02-25", "publish_status": "0", "recid": "30946", "relation": {}, "relation_version_is_last": true, "title": ["A Gain Measurement in the Liquid Based on Friis Transmission Formula in the Near-Field Region"], "weko_shared_id": null}
