Therefore, expHä k a NL = 1, so k a N = 2 pn where n is an integer. So k = (5.18) 2 pn a N = 2 pn L were, a N = L is just the length of the system. Notice here that k and k + 2 p’a gives exactly the same wave, expBä k + (5.19) 2 p a asF = expHäk as + ä2 psL = expHäk asLexpHä2 psL = expHäk asL So we will only need to consider -p’a < k ...
