A 3‐D non‐uniform time step locally one‐dimensional finite‐difference time‐domain (NUTS LOD‐FDTD) method is presented. Unlike conventional and the other LOD‐FDTD methods, NUTS LOD‐FDTD method employs NUTS for different periods during the simulation. The update equation of NUTS LOD‐FDTD method with arbitrary time step is given. Numerical results are provided to compare with conventional LOD‐FDTD method and trade‐off between efficiency and accuracy for different NUTSs.
