Abstract

This paper outlines improvements required in the modal decomposition equivalent circuit modelling (MDECM) method to simulate complex periodic structures at high frequencies as THz. It discusses initial approximations used by the method and whether they should be retained. Finally, in comparing the results of Modal Decomposition Equivalent Circuit Method (MDECM) to commercial computational electromagnetic (CEM) software, a measure is made of simulation speeds and match of results for both a free and capacitively-loaded slot-ring.
