    Transmission spectra changes produced by decreasing compactness of opal-like structures
    (AIP Publishing, 2009) Andueza Unanua, Ángel María; Echeverría, R.; Morales Zimmermann, Paola Andrea; Sevilla Moróder, Joaquín; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    Artificial opal-like structures based on spheres and colloidal particles have been fabricated in a controlled way, presenting optical band-gap properties in the optical frequency range. Nonclose packed artificial opals have also been fabricated and studied recently. In order to gain a better understanding of these phenomena, we have studied macroscopic models of nonclose packed fcc lattices using glass spheres (ε = 7) of 8 mm diameter, and measuring in the microwave region from 10 to 30 GHz. The results have shown a Bragg resonance tunable with filling factor of the opal, and a strong rejected band similar, also present in close packed samples, much less affected by compactness. The relation of this high order band with spheres single layer behavior is also discussed

    Erratum: “Transmission spectra changes produced by decreasing compactness of opal like structures” J. Appl. Phys. 105, 024910 (2009)

    Performing a systematic review of our experimental data, we have realized that we introduced a significant mistake in our abovementioned publication. Figure 3 did not correspond to the situation described, and should be changed by one here included. The corrected data do not invalidate the conclusions presented in the original publication, even more they are reinforced.
