Paper Abstract

A composite structure obtained by depositing a Columnar Thin Film (CTF) on a transparent substrate with a periodic array of rectangular grooves of infinite length can function as a narrowband, linear-polarization rejection filter. This device discriminates between the linear-polarization states of an incident plane wave, so that linearpolarization high-quality filters with extremely narrow bandwidths can be designed. Furthermore, the filter response can be tuned by varying the angle of incidence.
