title: Experimental demonstration of resonant anomalies in diffraction from two-dimensional gratings.
abstract: Resonant effects in diffraction from two-dimensional dielectric gratings is demonstrated experimentally. A two-layer structure, which consists of a uniform guiding layer and a grating layer, yielded symmetric, low-sideband resonance that is suitable for narrow-band filter applications. Excellent agreement between measured and calculated spectral and angular dependence is obtained.
