Abstract :
This paper introduces a novel method of incorporating macromodels into the FDTD (finite difference time domain) algorithm. Macromodels are generated by model order reduction applied to state equations in the FDFD method for a higher resolution grid of the chosen subspace. This approach allows one to analyse a structure with a locally denser mesh and thus increases calculation accuracy and reduces the overall computation time.
