Abstract
At large densities or large distances from the transmitting antenna it is observed that resonance cones, instead of being a single sharp peak, become spatially modulated by a multiperiod interference pattern; this interference pattern can dominate over the phasing imposed by a grill antenna. A simple theory shows that this effect occurs when and that it is caused by electromagnetic terms neglected in the electrostatic approximation.
