Returning to Section 9.1, let where the wavefront shapes are not explicitly specified, and E Ë 1 and E Ë 2 are complex vectors depending

Returning to Section 9.1, let

where the wavefront shapes are not explicitly specified, and E^Ëœ₁ and E^Ëœ₂ are complex vectors depending on space and initial phase angle. Show that the interference term is then given by

You will have to evaluate terms of the form

for T >> Ï„ (take another look at Problem 3.15). Show that Eq. (9.109) leads to Eq. (9.11) for plane waves.

-iot ,(7, 1) = ,(7)eiat 2(7, t) = 2( )eiat and (9.109)
