Abstract
This paper designs a two-dimensional (2D) photonic crystal based THz bandpass filter (BPF). Fine bandpass property is realized by introducing symmetrical point defect on both sides of a line defect 2D photonic crystal to the forming of resonant cavity. This kind of 2D photonic crystal filter has large bandwidth and its out-band rejection properties can be further improved by introducing more pairs of symmetric point defects to realizing the cascading of more resonant cavity. The designed filter can satisfy application needs in THz communication and radar systems.
