Abstract :
In a uniform array of antiguides, when codirectional leaky waves from adjacent elements add in phase, each element equally couples to all others, causing the fundamental-mode near field to become uniform. The resonance condition is derived. When codirectional leaky waves are out of phase, coupling is only nearest-neighbour, causing the fundamental-mode near-field intensity envelope to be cosine-like. The consequences are discussed
