A Dielectric Loaded Slow Wave Structure for Separation of Relativistic Particles

Dielectric loaded waveguides of rectangular cross section are considered as synchronous traveling wave particle separators. These structures support two linearly independent modes: those which have no electric field perpendicular to the dielectric, and those which have no magnetic field perpendicular to the dielectric. Both modes have suitable transverse deflection forces with phase velocities which can be slower than the speed of light. Degeneracies and dispersion relations are discussed. The theoretical conclusions are supported by experimental studies which include slotted line and bead perturbation measurements.
