An optical surface rarely presents the idea optical behavior desired for the system in which it is employed. Modifying
these properties is the task of an optical coating and virtually all optical surfaces in all optical systems carry such
treatments. Most often the coating consists of a number of thin layers exhibiting interference effects that yield a suitable
performance. Coating performance is constrained by the normal properties of interference. Such behavior could benefit
considerably from the use of metamaterials and particularly those exhibiting a negative index of refraction.
Unfortunately such true negative index still appears elusive. Negative refraction has been convincingly demonstrated
particularly for p-polarization and this is certainly useful in a number of applications but metamaterials have not so far
yielded the complete set of properties representing the true negative index that could transform the field of optical

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
