Comment II on "Generation of focused, nonspherically decaying pulses of electromagnetic radiation"
The claim [H. Ardavan, Phys. Rev. E 58, 6659 (1998)] that a smooth, fast rotating source distribution can radiate with an intensity decaying more slowly than the inverse square distance violates a rigorous upper bound on intensity and is therefore false. The bound had been derived in response to earlier claims and the derivation is repeated here.
