It is well known that dipole coupling in periodic plasmonic nanoparticle arrays can produce narrow collective resonances at the wavelength corresponding to the Rayleigh anomaly, and spectral sensitivity to the environmental properties of these resonances makes them very attractive for sensing applications. Here we theoretically studied spectral properties of period nanoparticle array in transverse-magnetic polarization. If substrate is present, reflectance and dipole coupling between nanoparticles causes a band of transparency in transmission spectrum.
