    "abstract": "The normal mode theory of the transmission lines is applied to the studies of\nthe Four-Rod RFQ. This resonator consists of four quadrupole electrodes and\nstems. It can be simulated by the four-conductor shielded transmission line,\nwhich is loaded by sets of coaxial transmission lines corresponding to the\nsupport stems. The ideal case of the indefinite periodic Four-Rod RFQ is\nconsidered. Formulas for resonance frequency, the voltage distribution along\nthe electrodes and the shunt impedance are obtained.",
