(a) Optimized control sequence for harmonic beamforming of an ideal 16-dipole uniform array [16]. Corresponding fundamental and first sidebands normalized radiation patterns for power transfer in = −30°, 0°, 30° directions: (b) for the equally spaced array of Figure 4(a) and (c) for the unequally spaced array of Figure 4(b).
