EFFICIENT IMPLEMENTATION OF THE NUMERICALLY MATCHED LOADS INTO THE 3-D SPECTRAL-DOMAIN ANALYSIS USING TRIANGULAR SUBDOMAIN FUNCTIONS

A clever way to simulate Numerically Matched Loads is presented and ap plied in the mathematical framework of 3-D spectral domain analysis. T he numerically matched loads already have been developed in the partic ular case of the spectral domain approach using a set of subsectional rooftop expansion and testing functions in the moment method. In order to properly model more complicated structures, we propose in this let ter an extension of the the NML simulation where triangular subdomain functions are used as both expansion and testing functions in the mome nt method.
