In this paper, the amplitude and polarization of VLF waves at various places on the ground are calculated with an ionospheric model at high latitudes, through a full wave technique when various size of trapping cones are existing. Some results of the numerical calculation are presented. Major results are as follows : (1) Waves with an amplitude within 12 dB of the maximum intensity are found in an area of 300km (east-west direction)×400km (north-south direction) when some part of the trapping cone overlaps with the transmission cone. (2) The left-handed polarization wave can exist even within a distance of 100km from the point of maximum intensity, where the intensity is as strong as ∿ -10dB of the maximum intensity.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Electrical Engineering and Computer Science, Kanazawa University"},{"subitem_text_language":"en","subitem_text_value":"Department of Electrical Engineering and Computer Science, Kanazawa University"},{"subitem_text_language":"en","subitem_text_value":"Department of Electrical Engineering and Computer Science, Kanazawa University"},{"subitem_text_language":"en","subitem_text_value":"Department of Electrical Engineering II, Kyoto University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1987-03-01"}],"displaytype":"detail","filename":"KJ00000012717.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012717","url":"https://nipr.repo.nii.ac.jp/record/2164/files/KJ00000012717.pdf"},"version_id":"21d51ddc-d645-4581-a14d-8e6abf8bcf4f"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Propagation characteristics in the earth-ionosphere waveguide for VLF waves emitted from trapping cones at high latitudes","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Propagation characteristics in the earth-ionosphere waveguide for VLF waves emitted from trapping cones at high latitudes","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["401"],"pubdate":{"attribute_name":"公開日","attribute_value":"1987-03-01"},"publish_date":"1987-03-01","publish_status":"0","recid":"2164","relation_version_is_last":true,"title":["Propagation characteristics in the earth-ionosphere waveguide for VLF waves emitted from trapping cones at high latitudes"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:52:26.231823+00:00"}
