Article Description

In this paper, we used the ‘PWE band solver’ of the software package OPTIFDTD to find the photonic band gap of 2D annular photonic crystal biosensor. A Terahertz frequency range has been observed. The relationship between the band gap and the refractive index, which has been shown graphically, allows as to calculating the sensitivity which has been achieved 1.8774 (THz/RIU), and identifying any unknown biological analyte. Widening the widths of the ring holes of purposed structure, improve a higher sensitivity.
