    "abstract": "We investigate numerically optical properties of novel two-dimensional\nphotonic materials where parallel dielectric rods are randomly placed with the\nrestriction that the distance between rods is larger than a certain value. A\nlarge complete photonic gap (PG) is found when rods have sufficient density and\ndielectric contrast. Our result shows that neither long-range nor short-range\norder is an essential prerequisite to the formation of PGs. A universal\nprinciple is proposed for designing arbitrarily shaped waveguides, where\nwaveguides are fenced with side walls of periodic rods and surrounded by the\nnovel photonic materials. We observe highly efficient transmission of light for\nvarious waveguides. Due to structural uniformity, the novel photonic materials\nare best suited for filling up the outer region of waveguides of arbitrary\nshape and dimension comparable with the wavelength.",
