Abstract

In designing optical systems in the EO/IR wavelength region for conventional lens are most common and efficient when low F# and large field of view is desired. Conventional lenses are efficient in meeting optical response but come at a cost in size and weight and often are complex in nature (aberrations). In this paper we discuss alternatives to conventional lenses. We examine diffractive optics (DO), and explore resonating and diffractive periodic metalo-dielectric structures as an alternative lensing. An oscillator model is employed to interpret these structures, wavefront bending and a design approach is provided.
