As this antenna frequency is less than either the plasma frequency or the electron gyrofrequency (both nearly 300 kHz for a plasma density of 10(exp 9)/cu m and a magnetic field of 0.1 gauss), only certain modes can propagate as an electromagnetic (EM) wave, and the near field is dominated by electrostatic (ES) effects. Although a comprehensive self-consistent EM-ES simulation would be the desired goal, there are many computational challenges to be overcome, so we begin with a quasi-static simulation so as to sort out the dominant ES effects. We present antenna simulations using Nascap-2k modeling the plasma using both an explicit Particle-In-Cell (PIC) approach and a hybrid approach with PIC ions and fluid barometric electron densities. In the latter, electron plasma oscillations are suppressed, while in the former they are excited. Accuracy of the simulations is assessed by comparison with lower-dimensional simulations of similar cases.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0049206026","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-05-001E","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Science Applications International Corp."},{"subitem_text_value":"Science Applications International Corp."},{"subitem_text_value":"Air Force Research Laboratory Space Vehicles Directorate"},{"subitem_text_value":"Air Force Research Laboratory Space Vehicles Directorate"},{"subitem_text_value":"Radex, Inc."}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Science Applications International Corporation"},{"subitem_text_language":"en","subitem_text_value":"Science Applications International Corporation"},{"subitem_text_language":"en","subitem_text_value":"Air Force Research Laboratory Space Vehicles Directorate"},{"subitem_text_language":"en","subitem_text_value":"Air Force Research Laboratory Space Vehicles Directorate"},{"subitem_text_language":"en","subitem_text_value":"Radex, Inc."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Mandell, M.
