Summary

The effective integration of 3D dielectric fractal structures called Monger sponges with the localization function of electromagnetic waves was investigated. The stage 3 Menger sponge composed of epoxy resin including TiO2-SiO2 composite particles were fabricated by stereolithography and used as a unit structure. A simply integrated 7×7 arrangement of the unit structures showed no localization. The stage 4 Menger sponge which was constructed of 20 unit structures showed sharp attenuations of both reflection and transmission amplitudes at 14 GHz. The localization appeared for the 1/3 side shared structure of 3×3 stage 4 Menger sponges. The wavelength and frequency of the localized modes could be predicted using an empirical equation associated with the fractal geometry and spatially averaged dielectric constant The simply connected structure has no longer fractal geometry. It changes to a periodic structure. These results suggest that the localization of electromagnetic wave can be maintained when integrating Menger sponge structures without appearing a periodic geometry.
