Extraordinary high-Q resonances in the scattering by a dielectric slab containing a grating of circular cylinders

An infinite dielectric wire grating in free space is known to possess very high-Q resonances at the frequencies close to the Rayleigh anomalies. Still a practical implementation of such a resonator may require its embedding in a dielectric slab. In this paper, it is shown that this can bring a...
