Abstract: | In this paper we report the results of our systematic numerical study on the characteristics of a-metal-dielectric-metal slab waveguide with an embedded ID metallodielectric photonic crystal using finite difference time domain method. At low teraherz (THz) optical frequency, the result show that the sensitivity of the device depends significantly on the shape of the corresponding dielectric rod, which acts as a defect, and the distance between the two metallic rods. In this simulation, the optimum device sensitivity is obtained for a round shaped defect with a radius of 0.28 mm lattice constant of 0.35 mm and operational frequency of 2.69 THz which lies in the range of biomolecule vibrational mode. |
