In this letter, a modified domain decomposition finite-difference time-domain method based on weighted Laguerre polynomials (DD-WLP-FDTD) is proposed for nonuniform subdomain interfaces in TEz case with perfectly matched layer (PML) absorbing boundary condition (ABC). The feasibility and accuracy of this modified DD-WLP-FDTD method are confirmed by two numerical examples. The maximum of the error is less than 0.0008% compared to the results of the conventional WLP-FDTD method and the relative reflection error of the PML ABC is less than -64 dB.
