Abstract :
Periodical arrangements of longitudinally directed dipole particles over an infinite metal plane are considered. The dipoles, which may be small wire antennas or small thin longitudinal dielectric ellipsoids, are along a straight line and are close to each other, forming a dense dipole array. An analytical solution for waves propagating along this infinite dipole line structure is found. The system can be used as a transmission line with exotic and controllable properties.
