Abstract :
This paper presents both theoretical and qualitative comparison of the two most popular time-domain numerical methods for the analysis of electromagnetic problems: the transmission-line modeling (TLM) method and the finite-difference time-domain (FDTD). The comparison is based on the author´s experience as well as others. While TLM is a physical model based on Huygens´ principle using interconnected transmission lines, the FDTD is an approximate mathematical model directly based on Maxwell´s equations
