Abstract

We engineer anomalous conical diffraction (CD), occurring in discrete one-dimensional lattices with chargeconjugation symmetry when an exceptional point is in the proximity of the modes that compose the initial excitation. The evolving waveform propagates ballistically, acquiring a constant intensity profile within the boundaries of the spreading cone. The linear increase in the total intensity along the propagation direction is responsible for the generation of constant intensity CD.
