One-Step Leapfrog
Abstract—In this letter, an unconditionally stable one-step leapfrog alternating-direction-implicit finite-difference time-domain (ADI-FDTD) method for body of revolution (BOR) is proposed. It is more computationally efficient while preserving the properties of the original alternating-direction-implicit body of revolution finite-difference time-domain (ADI-BOR-FDTD) method. Due to the singularity, some field components on and adjacent to the axis are treated especially. To verify the accuracy and efficiency of the method, the scattered field from a PEC cylinder with a notch is calculated.
