Exploring the behavior of a matched load in the time domain

The purpose of a matched load is to produce maximum absorption of energy from a signal source or, equivalently, to minimize reflections from the load. The matched load originated as a circuit concept, but also plays a role in antenna design and performance. This note elaborates on the discussions by Bantin [1, 2], in which he used the idea to reduce late-time radiation from an impulsively excited dipole antenna. Illustrated explicitly here is how a matched load performs using the time-domain code TWTD (Thin-Wire Time Domain) [3].
