Nondiffracting or propagation-invariant beams are generated when a conical set of plane waves produced from points lying along a circle in an aperture plane interfere mutually. When the set of points along the circle are fractal, the generated nondiffracting beams possess fractality and power-law profiles. Their lateral intensity distributions and extension of the power-law beams are discussed numerically.
