transient electromagnetic method

transient electromagnetic method (TEM) An electromagnetic surveying method in which the source signal consists of a train of pulses rather than a continuous wave-form. Quasi-transient methods are used for continuous profiling (e.g. the INPUT method), while true TEM methods are most commonly used for depth soundings. It is a time-domain method.
