The proposed method will utilize gradiometric techniques in combination with a highly sensitive VLF\/LF broadband receiver to isolate these weak interactions. This work seeks to localize objects in three-dimensional space within the container and quantify the spatial resolution, as well as to assess the size and material properties of the objects.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Detection and Localization of Objects Concealed within Highly Conductive Media using VLF Scattering"}],"uid":"28475","created_gmt":"2020-01-08 21:13:38","changed_gmt":"2020-01-23 19:59:23","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-01-30T13:00:00-05:00","event_time_end":"2020-01-30T15:00:00-05:00","event_time_end_last":"2020-01-30T15:00:00-05:00","gmt_time_start":"2020-01-30 18:00:00","gmt_time_end":"2020-01-30 20:00:00","gmt_time_end_last":"2020-01-30 20:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434371","name":"ECE Ph.D. Proposal Oral Exams"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"},{"id":"1808","name":"graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
