# State conditions of no reflection???

Tue January 03, 2012
If some condition on the optical properties and number of the layer pairs is fulfilled, the wave can propagate through the interface between regions of indices ni and n without reflection. Given materials having na/nb less than n/ni, it is possible to pick the number of layer pairs, m, to satisfy the condition (at least approximately)
these layers are represented by their indices of refraction, na and nb, interposed between materials having indices ni and n.
this is complex discussion which requires elaborate study...beyond scope of much discussion here.
