Reduced Shift Operator Alternating Direction Implicit FDTD Applied to Plasma

In order to analyze the electromagnetic characteristics of plasma more efficiently, a novel FDTD called R-SO-ADI FDTD is proposed. The proposed method which is based on the shift operator technique has clear conceptions and simple formulae, and it saves CPU time and reduces the storage of the field components through combining the reduced formulation technique and the ADI scheme. Calculation results of the RCS of a perfectly conducting cylinder coated by plasma confirm the validity of the proposed method.
