Magnetic properties of infinitely long and wide slablike Josephson-junction arrays (JJA's) consisting of 2[ital N]+1 rows of grains are calculated for the dc Josephson effect with gauge-invariant phase differences. When [ital N] is large, the intergranular magnetization curve, [ital M][sub [ital J]]([ital H]), of the JJA's in low fields approaches that of uniform Josephson junctions with lengths equal to the thicknesses of the JJA's, but in a larger field interval, its amplitude is dually modulated with periods determined by the junction and void areas. [ital M][sub [ital J]]([ital H]) curves for small [ital N] are more complicated. The concept of Josephson vortices and the application of the results to high-[ital T][sub [ital c]] superconductors are discussed.
