Nonlocal and spontaneous material responses: Reply to comment on "Rigorous solution for transient propagation of electromagnetic waves through a medium: causality plus diffraction in time".
I reply to the Comment by Weiglhofer and Lakhtakia on Opt. Lett. 25, 995 (2000). I agree with the comment to such an extent that it is generally known that nonlocal effects and material response time have to be considered in using collective macroscopic material response parameters. However, I believe that the Comment is incomplete and bears no special connection with the study that I reported in the original Letter.
