(color online) Schematic diagram of the photonic crystal composite structure. Surface tubes are denoted by black circles and red circles. The outer radius and inner radius of each black circle are 0.16a and 0.1a, respectively; the outer radius and inner radius of each red circle are 0.16a and 0.13a, respectively.
