Summary

3D photonic fractals with the self-similar structure can localize electromagnetic waves completely without reflection and transmission. Such fractals of the Menger sponge structure were successfully fabricated with dielectric and metal media using CAD/CAM stereolithograpby. The localized frequency in dielectric Menger sponge structures is predicted using an empirical equation associated with the fractal geometry and spatially averaged dielectric constant, thus the frequency of the localized modes can be designed. For metal Menger sponge structures, the localized frequency could be determined mainly based on the geometrical factors. The localization mechanism in a photonic fractal is essentially different from the localization in a photonic crystal with the periodic structure. These new functionally structured materials of photonic fractals are considered to be applicable in a wide area of communication, information, energy, sensing, medical care, and others.
