    "abstract": "We show that the mode corresponding to the point of essential spectrum of the\nelectromagnetic scattering operator is a vector-valued distribution\nrepresenting the square root of the three-dimensional Dirac\u0027s delta function.\nAn explicit expression for this singular mode in terms of the Weyl sequence is\nprovided and analyzed. An essential resonance thus leads to a perfect\nlocalization (confinement) of the electromagnetic field, which in practice,\nhowever, may result in complete absorption.",
