Resonant effects in periodic gratings comprising a finite number of grooves in each period
We give numerical evidence of a kind of resonance that appears in infinite perfectly conducting gratings comprising a finite number of grooves in each period when illuminated by a normally incident p-polarized plane wave. This phenomenon is intimately connected with the particular distribution of th...
