Abstract :
The functionality of a slab radiator with low-index metamaterial substrate, is adjusted by a cluster of metallic cylinders positioned in the near-field region. A quasi-rigorous solution of the defined boundary value problem is proposed under the assumption of the small size of the rods. Beneficial characteristics concerning the total radiated power and the angle of directive emission have been detected in a number of different configurations. The related diagrams are independently validated and discussed.
