Line of periodically arranged passive dipole scatterers

Electromagnetic properties of line-periodical arrangements of passive loade d dipole scatterers are studied. An analytical solution for eigenwaves prop agating along infinite lines of dipoles is presented. Reflective properties of arrays are studied, regimes of narrow-band and wide-band strong reflect ion are identified and conditions for these operations found. Conditions of existence of guided-wave solutions are established. It is shown that in ar rays of capacitively-loaded antennas very rapid phase variations along the line are possible, which can possibly be used to realize wide-band superdir ective reflectors.
