Self-similar non-Bragg band gaps in fractal metamaterial multilayers

We investigate the appearence of non-Bragg band gaps in ID fractal photonic structures, specifically the Cantor-like lattices combining ordinary positive index materials and dispersive metamaterials. It is shown that these structures can exibit two new type of photonic band gaps with self-similarity...
