We consider a system of dispersionless and transparent plane-parallel
layers. We prove that the reflected and the transmitted spectra of suc
h a system are periodic and that, within each period, the intensity is
symmetric (even function) and the phase change is antisymmetric (odd
function). These properties are illustrated by application to a fracta
lly partitioned thin-film system. (C) 1996 Optical Society of America.
