The structures considered in this work act as electromagnetic filters, and as such, are of interest for use as thermophotovoltaic spectral control devices. For this application, absorption is of primary concern since it leads to reduced filter efficiency. This work focuses on the behavior of single-layer, free-standing FSS arrays comprised of circular apertures ͑holes͒ and circular loop apertures ͑rings͒. Numerical calculations of the transmission, reflection, and absorption characteristics of various arrays were carried out for wavelengths between 1 and 15 m using a commercial finite-element software package. Absorption effects were included using measured optical properties as input parameters to a surface impedance boundary condition. Analytical techniques were then employed to determine the absorption behavior in the static limit. An interesting result of this analysis is the fact that absorption at 15 m is predicted by the finite-element calculations to increase versus aperture radius ͑for fixed aperture separation͒, while in the static limit absorption was found ͑through the use of analytical techniques͒ to decrease. The results of the finite-element calculations were confirmed using another numerical method based on the periodic moment method. We are thus led to the conclusion that the qualitative relationship for absorption versus aperture radius must reverse for some frequency regime yet to be investigated.

“…1 Traditionally, such MDPCs were fabricated by stacking three or more layers of micron-scale metallic patch elements with intermediate dielectric spacers to achieve structures having a single resonant stopband with requisite band rejection properties ͑Ͼ10 dB͒. [2][3][4] More recently, MDPCs consisting of a dielectric substrate supporting a single planar periodic array of metallic patch elements, such as coupled 5 or uncoupled 6 dipoles, cross-dipoles, 7 and rings, 8 have also been demonstrated.…”

“…Furthermore, the resonant frequency can be tuned by the strain change in the copolymer films. 7 In general, 2D micro/submicroscale metallic patterns for FSSs are obtained by photolithography techniques, such as UV lithography, 8 electron-beam lithography, 3,[9][10][11] soft lithography, 12 and microlens projection lithography. A surface on which two-dimensional (2D) metallic patches or aperture elements are regularly arrayed, the socalled frequency selective surface (FSS), provides a method for constructing optical filters from a single layer of metallic structure.…”
