Abstract :
We carried out electromagnetic simulations of two-dimensional photonic-crystal waveguide (PCW) and coupled-resonator optical waveguide (CROW) structures created by changing the radii of air holes in a given row to investigate the effects in the terahertz region of the electromagnetic spectrum of introducing small quantities of molecules, such as DNA, in the air holes. The terahertz interaction with the analyte is modeled as a Lorentz medium. The finite-difference time-domain method with recursive convolution is used for numerical analyses
