Resonant effects in compound diffraction gratings

We give numerical evidence of a new kind of resonances that appear in infinite perfectly conducting gratings comprising a finite number of grooves in each period, when illuminated by a normally incident p-polarized plane wave. The resonances appear when a particular distribution of the phase of the...

520 3 |a We give numerical evidence of a new kind of resonances that appear in infinite perfectly conducting gratings comprising a finite number of grooves in each period, when illuminated by a normally incident p-polarized plane wave. The resonances appear when a particular distribution of the phase of the electromagnetic field inside the cavities takes place, and are identified as sharp peaks in the specularly reflected efficiency. These resonances are accompanied by a significant intensification of the interior field. The cavities considered are rectangular and the diffraction problem is solved for s and p polarization by using the modal method.  |l eng
