Problems<br />
Problem #1:<br />
Im[χ(k,ω)] must be defined on infinite ω interval for continuous <strong>time</strong> interval<br />
Solution:<br />
Extrapolate.<br />
Side effects:<br />
• χ(x,t) defined on continuous (infinitely narrow) <strong>time</strong> intervals.<br />
• Time “<strong>resolution</strong>” ∆t N = π/Ω max<br />
• Ω max plays role of pulse width.
