A fourth‐order finite‐difference time‐domain (FDTD) scheme is proposed for the solution of Maxwell's equations in cold plasma (Drude medium), based on the multistage method of Jameson, Schmidt and Turkel, which was originally introduced in the framework of fluid dynamics. First, the system of governing differential equations is formed as a general first‐order, operator‐based approach, and then a four‐stage algorithm is established. The accuracy of the method is verified in benchmark problems compared with analytical solutions and with the conventional second‐order FDTD algorithm.
