Coating a transparent substrate by a transparent thin film to produce a given transmission differential phase retardance without diattenuation for obliquely incident monochromatic light

Phase retarders for optical communications (C-band & L-band)

“…The third row shows a 5% change on the actual thin film thickness d 1 . The actual thin film thickness d 1 is found from the normalized thin film thickness, ζ1 [11]. Such an error has changed the phase shift from 90 o to 134.38 o .…”
