Abstract
The present invention relates to electromagnetic meta-material structures to serve as linear polarization sensitive mirrors. Two distinct classes have been developed, including: 1) a phase cohering reflector which maintains the phase of both polarization states with a controlled delay between polarization states, and 2) a phase de-cohering reflector which preserves the phase of one polarization state and destroys the coherence in the other. These reflective structures enable mitigation of spurious resonances in dual-polarization optical systems and phase compensation between polarization states. These polarization control structures have applications in absorber coupled detectors and receiver systems for space-borne and sub-orbital remote sensing applications.
