Fast Transient Analysis of Nonuniform Multiconductor Transmission Lines Using HIE-Block-LIM

This letter describes a hybrid implicit-explicit block latency insertion method (HIE-block-LIM) for the fast simulation of nonuniform multiconductor transmission lines (MTLs). In the HIE-block-LIM, an implicit difference method is used with respect to the current variables in the y-direction, and an explicit method is adopted to update the other variables. The HIE-block-LIM can alleviate a time step size limitation of the existing block-LIM by taking both advantages of the explicit and implicit difference methods. Numerical results show that the HIE-block-LIM is suitable for the fast simulation of the nonuniform MTLs.
