The model under study was formulated by relying on the index change in the refractive index (RI) because of the change in the sample that infiltrated the cavity. The index of refraction change is accompanied by modifying the resonant wavelength. The recommended model has considered the simple shape and ease of manufacture, along with other characteristics such as sensitivity and a low detection limit. The results report a high sensitivity of S = 546.72 nm\/RI unit (RIU), a high quality factor of Q = 2066.24, a low detection limit of DL = 1.44 \u00d7 10\u22124 RIU, and a high value of transmission of 97%, which are considered to be sufficient and efficient in detecting measured material. This proposed model provides many opportunities and is promising for the manufacture of different types of sensing detection devices.<\/jats:p>","DOI":"10.3390\/sym12091480","type":"journal-article","created":{"date-parts":[[2020,9,10]],"date-time":"2020-09-10T22:58:01Z","timestamp":1599778681000},"page":"1480","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["High-Sensitivity Capsule-Shaped Sensor Based on 2D Photonic Crystals"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5308-6926","authenticated-orcid":false,"given":"Mouhssin","family":"Maache","sequence":"first","affiliation":[{"name":"Laboratoire d\u2019Analyse des Signaux et Syst\u00e8mes, Universit\u00e9 Mohamed Boudiaf-M\u2019sila, BP.166, Route Ichebilia, M\u2019sila 28000, Algeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3544-2434","authenticated-orcid":false,"given":"Yousef","family":"Fazea","sequence":"additional","affiliation":[{"name":"Internetworks Research Laboratory, School of Computing, Universiti Utara Malaysia, Sitok 06010, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ismail","family":"Bile Hassan","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Cybersecurity, Metropolitan State University, 700 East Seventh Street, Saint Paul, MN 55106, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2067-9519","authenticated-orcid":false,"given":"Ammar Ahmed","family":"Alkahtani","sequence":"additional","affiliation":[{"name":"Institute of Sustainable Energy (ISE), Universiti Tenaga Nasional (UNITEN), Selangor 43000, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8896-547X","authenticated-orcid":false,"given":"Ikram","family":"Ud Din","sequence":"additional","affiliation":[{"name":"Department of Information Technology, The University of Haripur, Haripur 22620, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"69","DOI":"10.1007\/s13320-018-0479-8","article-title":"Design and Analysis of 2D Photonic Crystal Based Biosensor to Detect Different Blood Components","volume":"9","author":"Arunkumar","year":"2018","journal-title":"Photon Sens."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"102478","DOI":"10.1016\/j.rinp.2019.102478","article-title":"High-sensitivity ultra-quality factor and remarkable compact blood components biomedical sensor based on nanocavity coupled photonic crystal","volume":"14","author":"Mohammed","year":"2019","journal-title":"Results Phys."},{"key":"ref_3","doi-asserted-by":"crossref","unstructured":"Romano, S., Lamberti, A., Masullo, M., Penzo, E., Cabrini, S., Rendina, I., and Mocella, V.
