A main purpose of the\nsimulations is to predict particular lattice structures to achieve\nmaximal bandgaps. This target is a challenge as the computations are\nhighly time-consuming and many tuning parameters are involved. These\ntuning parameters include structure parameters in the photonics\ncrystal lattices and algorithmic performance parameters in the\neigenvalue solvers. To identify the optimal lattice structures and the\noptimal algorithm combinations, we use several statistical tools to\nmodel the unknown response functions of the tuning parameters. Tools\narising in design and analysis of computer experiments will be\ndiscussed to show the details of the schemes. Promising numerical\nresults will also be presented to justify the proposed schemes.\n\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Parameters Auto-Tuning in Three Dimensional Photonic Crystal Simulations"}],"uid":"27187","created_gmt":"2012-02-08 16:43:58","changed_gmt":"2016-10-08 01:58:00","author":"Anita Race","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2012-02-13T10:00:00-05:00","event_time_end":"2012-02-13T11:00:00-05:00","event_time_end_last":"2012-02-13T11:00:00-05:00","gmt_time_start":"2012-02-13 15:00:00","gmt_time_end":"2012-02-13 16:00:00","gmt_time_end_last":"2012-02-13 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EHost: Jeff Wu \u003Ca href=\u0022mailto:jeffwu@isye.gatech.edu\u0022\u003E\u0026lt;jeffwu@isye.gatech.edu\u0026gt;\u003C\/a\u003E\n\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
