These scholarships are awarded to U.S. graduate students working on collaborative research with a French institution.\u003C\/p\u003E\u003Cp\u003EA Ph.D. student in the School of Electrical and Computer Engineering at Georgia Tech, Keilman is conducting research on photonic crystals with his Ph.D. advisor David S. Citrin (who is temporarily based at the Georgia Tech-Lorraine campus) and with researchers at\u0026nbsp;\u00c9cole Polytechnique in Palaiseau, France.\u003C\/p\u003E\u003Cp\u003EPhotonic crystals are\u0026nbsp;periodic arrangements of dielectrics. Analogous to the band gap that may exist\u0026nbsp;for electrons in solid materials,\u0026nbsp;photonic crystals may exhibit a photonic band gap\u2013a range of frequencies where light is unable to propagate\u0026nbsp;through the structure. Thus, of the various applications of photonic crystals, one is to exclude light within a given frequency band.\u003C\/p\u003E\u003Cp\u003EKeilman\u0027s\u0026nbsp;research\u0026nbsp;is focused on how the\u0026nbsp;properties\u0026nbsp;of\u0026nbsp;photonic crystals are degraded by the inevitable presence of disorder, such as uncontrolled variations in the dielectric\u0026nbsp;constant and slight discrepancies in the position and size of the constituent parts. Disorder tends to permit light to propagate in the photonic band gap of the otherwise perfect photonic crystal.\u003C\/p\u003E\u003Cp\u003EKeilman is exploring structures that look ordered when one zooms in on a\u0026nbsp;small\u0026nbsp;region, but shows considerable disorder when one zooms out. Such structures may provide some of the\u0026nbsp;benefits\u0026nbsp;of ordered photonic crystals while relaxing the stringent\u0026nbsp;requirements\u0026nbsp;imposed in fabricating perfect structures.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EECE Ph.D. student Jacob Keilman has received a Chateaubriand Scholarship, which is awarded by the Embassy of France in the United States. \u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"ECE Ph.D. student Jacob Keilman has received a Chateaubriand Scholarship, which is awarded by the Embassy of France in the United States."}],"uid":"27241","created_gmt":"2014-06-20 15:52:45","changed_gmt":"2016-10-08 03:16:37","author":"Jackie Nemeth","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2014-06-20T00:00:00-04:00","iso_date":"2014-06-20T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"304311":{"id":"304311","type":"image","title":"Jacob Keilman","body":null,"created":"1449244609","gmt_created":"2015-12-04 15:56:49","changed":"1475895009","gmt_changed":"2016-10-08 02:50:09","alt":"Jacob Keilman","file":{"fid":"199651","name":"jacob_keilman.jpg","image_path":"\/sites\/default\/files\/images\/jacob_keilman_0.jpg","image_full_path":"http:\/\/tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/jacob_keilman_0.jpg","mime":"image\/jpeg","size":4396335,"path_740":"http:\/\/tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/jacob_keilman_0.jpg?itok=B0wPbCmD"}}},"media_ids":["304311"],"related_links":[{"url":"http:\/\/www.ece.gatech.edu\/","title":"School of Electrical and Computer Engineering"},{"url":"http:\/\/www.gatech.edu\/","title":"Georgia Tech"},{"url":"http:\/\/www.georgiatech-metz.fr\/","title":"Georgia Tech Lorraine"},{"url":"http:\/\/www.polytechnique.edu\/jsp\/accueil.jsp?CODE=36392593\u0026LANGUE=1","title":"\u00c9cole Polytechnique"}],"groups":[{"id":"1255","name":"School of Electrical and Computer Engineering"}],"categories":[{"id":"134","name":"Student and Faculty"},{"id":"8862","name":"Student Research"},{"id":"145","name":"Engineering"},{"id":"149","name":"Nanotechnology and Nanoscience"},{"id":"135","name":"Research"},{"id":"150","name":"Physics and Physical Sciences"}],"keywords":[{"id":"54311","name":"Ecole Polytechnique"},{"id":"109","name":"Georgia Tech"},{"id":"166855","name":"School of Electrical and Computer Engineering"}],"core_research_areas":[{"id":"39451","name":"Electronics and Nanotechnology"},{"id":"39471","name":"Materials"}],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EJackie Nemeth\u003C\/p\u003E\u003Cp\u003ESchool of Electrical and Computer Engineering\u003C\/p\u003E\u003Cp\u003E404-894-2906\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022mailto:jackie.nemeth@ece.gatech.edu\u0022\u003Ejackie.nemeth@ece.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":["jackie.nemeth@ece.gatech.edu"],"slides":[],"orientation":[],"userdata":""}}}
