A wt o d mi ensional square photon i ry stalw ith latti e onstant 0. 3mm w as analyzed, w hi h an be a h ieved omparatively eas ily in te hnology. Itw as show n that the entral frequen y and thew idth of the photon i band gap ( PBG ) in reasew ith the rad ius of opper ylinder from 0. 1to 0. 3, and when the radius w as 0. 32, two PBGs w ere found w ith in the range from 0TH z to 2TH z. Th is resear h provides a theoreti basis for the developm ent of TH z devi es.
