Measured (solid lines) and simulated (dotted lines) room temperature near-normal emittance of the fabricated W PhC Sample I (r = 0.48 μm, a = 1.22 μm, d = 1.30 μm) and W PhC Sample II (r = 0.55 μm, a = 1.40 μm, d = 1.60 μm). The emittance is approximated from measurements of near-normal specular reflectance via Kirchhoff’s Law.
