A novel 3-D higher-order finite-difference time-domain framework with complex\nfrequency-shifted perfectly matched layer for the modeling of wave propagation\nin cold plasma is presented. Second- and fourth-order spatial approximations\nare used to discretize Maxwell's curl equations and a uniaxial perfectly\nmatched layer with the complex frequency-shifted equations is introduced to\nterminate the computational domain. A numerical dispersion study of second- and\nhigher-order techniques is elaborated and their stability criteria are\nextracted for each scheme. Comparisons with analytical solutions verify the\naccuracy of the proposed methods and the low dispersion error of the\nhigher-order schemes.\n
