“…It is to be noticed that our asymptotic analysis still holds when applied to the study of crystals bounded solely in one direction (bi-gratings) or two directions (rods). It is then straightforward to study the homogenization of bigratings: (the reader may refer to [21] or [22] to find adapted radiation conditions), which is a natural extension of the works led in [3] and [5]. Work is also proceeding on the homogenization of finite photonic crystals, whose basic cell is not paralellepipedical, by the use of differential forms.…”

“…Original designs relied on simple gratings [11][12][13][14][15][16][17] for their working mechanism. These gratings induced first-order and second-order air gap mode resonances which interact with the incident light to perfectly absorb it.…”

“…These gratings induced first-order and second-order air gap mode resonances which interact with the incident light to perfectly absorb it. The main drawback of these original designs was the lack of tunability [15], polarisation dependence [3], and narrow bandwidth [7], and they were extremely dependent on the angle of the incident light [3][4][5][6][7][11][12][13][14][15][16][17]. Many new devices and mechanisms have been proposed, presented, and improved on since then; we will discuss them here.…”

In the past decade, the realisation of negative index materials has initiated extensive research into metamaterials. Perfect absorbers and reflectors are of particular interest as their usefulness is endless in a range of different fields and devices. Since it was originally shown that a device can achieve unity absorption of electromagnetic waves, it has become a hot area of research to develop perfect absorbers based on polarisation independence and incident angle independence, at a range of frequencies from microwave to optical ones. The amazing performance, flexibility, and tunability of these metamaterials will be discussed here, by presenting the different designs and working mechanisms that have been realised up to now. Their limitations and shortcomings will be addressed and future plans for perfect absorbers and reflectors will be suggested.

“…Derrick 12 17 presented numerical results for metallic inductive grids based on the rigorous coupled wave analysis (RCWA) 18 . Their modeling was done principally for the case of rectangular scatterers and included the dielectric expansion changes suggested by Li 19 to improve the convergence of the algorithm.…”

AGENCY USE ONLY (Leave Blank)REPORT DATE ABSTRACT (Maximum 200 words)Periodic structures were designed, fabricated and characterized to control the emission of electromagnetic radiation. These electromagnetic crystals were fabricated using interferometric lithography, a technique that lends itself to large area periodic structures. The characterization was done using a Fourier Transform Infra-red Spectrometer. Extensive rigorous modeling was developed based on reigorous coupled-wave analysis and was shown to provide a route to "design-to-performace" for these structures.

The goal of the HIDE program is to directly control the emissivity of an object. The fabrication of the crystals is based on interferometric lithography (see attachment for a description of this method). This is a technique whereby two laser beams are interfered to establish a periodic pattern on a sample. Using standard lithography techniques, the pattern is transferred to the chosen material system. Currently, the material system of choice is silicon on sapphire and bulk silicon. In these material systems, we are able to etch a periodic pattern of air holes in the silicon sample. In addition, the material system can be metallized to obtain higher responsivity in a smaller area. Keep in mind that the system being tested is simply a two-dimensional electromagnetic crystal that is finite in the third dimension. Remarkably, the need for a three-dimensional structure to achieve the desired result is not apparent. We have independently shown that omni-directional stop bands can be achieved using simply a one-dimensional stack of alternating dielectric material. Although a "cute" solution, the utility of such a solution remains to be...
