Abstract

This work presents a novel numerical scheme for the acceleration of the 2-D Transmission-Line Matrix method. The idea is the use of controlled leaps in the time step in order to achieve faster processing. The leaps are numerically stable and may result in significant CPU savings. In addition to the adjustable time step, the procedure becomes more efficient by using model reduction with Schur decomposition. The technique was validated by the calculation of a microwave filter and subsequent comparison to the normal TLM results.
