“…Researchers start using circles, squares or spheres as scatterers in simulation and fabrication processes. Based on these studies, many excellent structures have been designed and studied by computation and simulation, such as diamond structure and hexagon structure [3][4][5][6][7]. Importantly, optimal bandgaps can be obtained and adjusted by varying the refractive index or using anisotropy in the dielectric [8][9][10].…”

Scatterer is the basic element of photonic crystal. With operating frequency f =1THz (wavelength λ =300μm), we proposed sector as scatterer and analyzed the influence of parameters to photonic bandgap (BPG) for the structures of pillars in air, such as the center radius of sector r, width of sector d, and central angle of the sector θ. For two-dimensional hexagonal arrays, the absolute BPG width and the relative BPG width were demonstrated by the three parameters in TE mode, respectively.
