摘要：
A terahertz (THz) resonator composed of parallel metal plates with gratings is analyzed using the locally one-dimensional finite-difference time-domain (LOD-FDTD) method with a perfect electric conductor (PEC) boundary condition. A defect section is introduced into the gratings, yielding a strong resonance in the band gap of the gratings. A shift of the resonance frequency caused by a large time step size can be compensated with the help of the dispersion control parameters. The computation time of the PEC-LOD-FDTD is reduced to only 350/ 0 of that of the traditional explicit FDTD.
