3-D non-uniform time step locally one-dimensional FDTD method

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 a...

Description
Summary: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.
