“…The NEPTUNE code [1] has been created based on the new algorithm and used to explore its effectiveness for simulation. The code includes a model for the electron beam similar to that used in the NRL code TESLA, where an ensemble of macro-particles is distributed uniformly over both beam cross-section and entrance phase with respect to the RF field.…”

“…However, the ADI-FDTD method is a split-step method while the conventional explicit FDTD method is a leapfrog method. Recently, the leapfrog ADI-FDTD method was introduced to better synchronize the conventional explicit FDTD and ADI-FDTD methods [28][29][30]. As is the case of the ADI-FDTD method, the leapfrog ADI-FDTD method retains the usage of the School of E. E. E Nanyang Technological University…”

First, I would like to express my sincere gratitude to my supervisor, Assoc. Prof. Tan Eng Leong, for introducing me to the fascinating area of unconditionally stable finite-difference time-domain methods, and also for his guidance throughout my Ph.D. candidature. The completion of this thesis would not have been possible without his valuable advice and motivation. I would like to thank DSO National Laboratories, Singapore for the scholarship provided. I would also like to thank the faculty and laboratory staffs at the School of Electrical and Electronic Engineering for their support and assistance. Last but not least, I am sincerely grateful to my parents and family members for their encouragement and understanding.

Developments of fundamental locally one-dimensional finite-difference time-domain methods for transmission lines and lumped elements

This thesis presents the developments of fundamental locally one-dimensional finitedifference time-domain (FLOD-FDTD) methods for transmission lines and lumped elements. Unlike explicit FDTD method, the FLOD-FDTD method can use time step larger than Courant-Friedrichs-Lewy (CFL) limit. It also achieves higher efficiency and simplicity with matrix-operator-free right-hand sides (RHS) compared with the conventional LOD-FDTD method. The updating equations of the FLOD-FDTD method incorporating resistors, inductors and capacitors are derived. In addition to the three commonly used lumped elements, explicit FDTD method and FLOD-FDTD method incorporated with memristor are also developed. Memristor is regarded as the fourth lumped element which links charge and flux. The update equations are derived based on Maxwell's equations and the physical model given by Hewlett-Packard (HP) lab. Numerical examples including transmission lines and various lumped elements are provided to show the trade-off between efficiency and accuracy of the proposed 3-D FLOD-FDTD method.
