Summary

Photonic fractal with self-similar pattern of dielectric materials can localize strongly electromagnetic wave. We have fabricated Menger-sponge type photonic fractals composed of epoxy with titania-silica particles dispersion by using stereolithography of a CAD/CAM system. In the Menger-sponge structure, the cubic body of 81 mm in edge length with square holes of 1, 3, 9 and 27 mm in edge size to realize the self-similar structure with fractal dimension 2.7. The real Menger-sponge samples with fractal stage number 1, 2, 3 and 4 localized the microwave of 9.5, 10.5, 12.0 and 13.5 GHz, respectively. Those localized mode's frequencies showed good agreements with the calculated ones form an empirical equation using the cube size, number of stage and the effective dielectric constant Intensity profiles of electric field at the inner and outer space of the Menger-sponge showed the perfect confinement of the wave energy.
