It is shown that a single-layer array of high electric permittivity (high-e) rods more than 97% of the energy of optical waves with arbitrary incident angle. The occurrence of the phenomenon depends on the construction of two particular grating modes (GMs) in the array which two corresponding transmitted wave components that cancel each other. The construction of the dominant GMs in the array benefits from of the angular momenta components opposite signs in high-e particles. The effect offers a possibility for improving the optical elements integration level in the on-chip optical circuits.
