Here, we report the first experimental observation of an accidental electromagnetic BIC in a one-dimensional periodic chain of coaxial ceramic disks. We show that the accidental BIC manifests itself as a narrow peak in the transmission spectra of the chain placed between two loop antennas. We demonstrate a linear growth of the radiative quality factor of the BICs with the number of disks that is well described with the developed tight-binding model. We estimate the number of disks when the radiation losses become negligible in comparison to material absorption and, therefore, the chain can be considered as practically infinite. The presented analysis is supported by near-field measurements of the BIC profile. The obtained results provide useful guidelines for practical implementations of structures with BICs opening up horizons for the development of radio-frequency and optical metadevices.","lang":"eng"}],"oa":1,"article_number":"034041","fulldoi":"https://doi.org/10.1103/physrevapplied.15.034041","date_created":"2026-03-30T12:22:47Z","issue":"3","day":"15","scopus_import":"1","quality_controlled":"1","OA_type":"green","language":[{"iso":"eng"}],"publication_status":"published","volume":15,"type":"journal_article","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2010.15167","open_access":"1"}],"extern":"1"}
