  text: Being a general wave phenomenon, bound states in the continuum (BICs) appear
    in acoustic, hydrodynamic, and photonic systems of various dimensionalities. 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.
