text: The method of correctively modifying toward a desired predetermined effective value the electrical thickness of a dielectric material wall which initially approximates said value, said wall being adapted to permit propagation of a beam of electromagnetic wave energy of selected wavelength transversely therethrough, comprising the steps of measuring deviations from said value in the different areas of the wall to be traversed by the beam, and applying to one side of the wall, at discrete noncontiguous locations, within those areas having such deviations greater than a predetermined amount, thickness modification corrections which produce a small fractional charge in the dielectric material thickness, and thereby in the electrical thickness, of said wall only in the specific areas actually occupied by such corrections but which by their presence thereby also change the effective dielectric thickness also of areas immediately surrounding such specific areas, with respect to the net effect thereof on the wave fronts of energy in such propagating beam.
