The traveling-wave current (TWC) has served as one kind of "canonical" current distribution for simulating the behavior of a wire antenna, as has the standing-wave, sinusoidal current filament (SCF). Besides yielding closed-form solutions for their far-field patterns and radiated powers, the sinusoidal current filament and traveling-wave current can approximate the current on a wire antenna that is appropriately excited. The traveling-wave current's power distributions, as obtained using the induced EMF method and the FARS (far-field analysis of radiation sources) method, together with similar results for the sinusoidal current filament, are discussed in this brief note
