Abstract
A combination of the transmission line matrix (TLM) and the transverse wave formulation (TWF) method based on a diakoptics approach is presented for efficient modeling of multiscale and multilayered planar structures. The formal similarities of TLM and TWF enable a direct diakoptics approach, partitioning the simulation domain into a TLM and a TWF region. The computationally inefficient time-domain convolution of the TLM wave pulses with the impulse responses at the domain separation interfaces is replaced by a vector multiplication in frequency-domain leading to a considerable reduction of the total simulation time.
