We consider periodic waves in miscible two-component Bose-Einstein condensates with repulsive nonlinear interaction constants. Exact one-phase solution is found for the case when all these constants are equal to each other (i.e., for the Manakov limit). New types of nonlinear polarization waves are considered in detail. The connection of the solutions found with experimentally observed periodic structures in two-component condensates is discussed.
