Equivalent layers in oblique incidence: the problem of unsplit admittances and depolarization of partial reflectors.
Ohmer's algorithm for the complete exact synthesis of three-layer equivalent periods has been generalized for oblique incidence, and a theory was developed for periods with unsplit equivalent admittances, observing simultaneously the corresponding equivalent phase thicknesses. In a parallel development general conditions were deduced for the depolarization of outer media by quarterwave extensions of the central system. In combination, these building blocks enable the design of depolarized partial reflectors. A number of concrete designs are presented on various reflection levels.
