Phase resonances in compound metallic gratings

We study the phase resonances that appear in infinite conducting gratings comprising a finite number of grooves in each period (compound gratings), when illuminated by a p-polarized plane wave. In particular, we investigate a surface that separates a lossy conductor from a dielectric isotropic mediu...
