    "abstract": "By a generalized bidirectional decomposition method, we obtain many new\nSuperluminal localized solutions to the wave equation (for the electromagnetic\ncase, in particular) which are suitable for arbitrary frequency bands; various\nof them being endowed with finite total energy. We construct, among the others,\nan infinite family of generalizations of the so-called \"X-shaped\" waves.
