Infrared metamaterial arrays containing Au elements immersed in a medium of benzocyclobutene (BCB) were fabricated and selectively etched to produce small square flakes with edge dimensions of approximately 20 mu m. Two unit-cell designs were fabricated successfully: one employed crossed-dipole elements while the other utilized square-loop elements (the latter design was symmetric about a Cr ground plane). Infrared spectral reflectivity measurements from collected flakes were compared to infinite-surface simulations in Ansoft HFSS and spectral reflectance measurements of full array samples. Good agreement was found between modeled and experimental resonant behavior when taking into account the proportionality of flakes filling the input aperture of the measurement apparatus.
