The shoulder-coupled resonant cavity is introduced in the photonic crystal, which is infiltrated with magnetic fluid. Through monitoring the shift of resonant wavelength, the magnetic field sensing is realized. According to the designed infiltration schemes, both the magnetic field sensitivity and full width at half maximum increase with the number of infiltrated air holes. The figure of merit of the structure is defined to evaluate the sensing performance comprehensively. The best structure corresponding to the optimal infiltration scheme with eight air holes infiltrated with magnetic fluid is obtained.<\/jats:p>","DOI":"10.3390\/s16122157","type":"journal-article","created":{"date-parts":[[2016,12,16]],"date-time":"2016-12-16T10:55:28Z","timestamp":1481885728000},"page":"2157","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["A Photonic Crystal Magnetic Field Sensor Using a Shoulder-Coupled Resonant Cavity Infiltrated with Magnetic Fluid"],"prefix":"10.3390","volume":"16","author":[{"given":"Delong","family":"Su","sequence":"first","affiliation":[{"name":"College of Sciene, University of Shanghai for Science and Technology, Shanghai 200093, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0349-067X","authenticated-orcid":false,"given":"Shengli","family":"Pu","sequence":"additional","affiliation":[{"name":"College of Sciene, University of Shanghai for Science and Technology, Shanghai 200093, China"},{"name":"Shanghai Key Laboratory of Modern Optical System, University of Shanghai for Science and Technology, Shanghai 200093, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lianmin","family":"Mao","sequence":"additional","affiliation":[{"name":"College of Sciene, University of Shanghai for Science and Technology, Shanghai 200093, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhaofang","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Sciene, University of Shanghai for Science and Technology, Shanghai 200093, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kai","family":"Qian","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Hubei University for Nationalities, Enshi 445000, Hubei Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,12,16]]},"reference":[{"key":"ref_1","unstructured":"Rosensweig, R.E.
