    "abstract": "This paper presents theoretical results indicating that newly discovered\nnondiffracting beams we call X waves, can propagate in a confined space (wave\nguide) with specific quantized temporal frequencies. These results could have\napplications in nondispersive transmission of acoustic, electromagnetic\n(microwaves) and optical energy through wave guides as well as provide new\nlocalized wave functions of de Broglie waves in quantum mechanics.",
