Abstract :
We propose a locally conformal TLM cell that requires no change in the scattering algorithm and eliminates the time step constraint imposed by graded meshing. It also circumvents the need for time and space interpolations required by multi- and sub-gridding schemes. Simulation results confirm the accuracy and versatility of the approach.
