Time-domain finite methods are considered by many as the perfect candidates for the powerful, versatile, and accurate numerical simulation of complex electromagnetic phenomena. However, some concerns still remain about the accuracy of these methods, and questions keep being raised about their modeling versatility. By reviewing the key characteristics of several of these finite methods, and considering the various sources of the associated discretization and numerical error, we argue that their proper use permits the very accurate modeling of electromagnetic scattering and propagation phenomena associated with structures of electrical size and complexity beyond the capabilities of present frequency-domain. finite and integral equation methods.
