    "abstract": "The diffraction problem of a plane wave impinging on a grating formed by\nnested cavities is solved by means of the modal method, for $s$ and $p$\npolarization modes. The cavities are formed by perfectly conducting sheets that\ndescribe rectangular profiles. The electromagnetic response of the grating is\nanalyzed, paying particular attention to the generation of resonances within\nthe structure. The dependence of the resonances on the geometrical parameters\nof the grating is studied, and results of far and near field are shown. The\nresults are checked and compared with those available in the literature for\ncertain limit cases.",
