The review of electromagnetic box coupling to transmission strains is an
important challenge in electromagnetic compatibility. using the transmission line (TL) approximation thought has accredited the answer of a giant diversity of difficulties (e. g. lightning and EMP interplay with strength lines). despite the fact that, the continuous bring up in working frequency of goods and higher-frequency resources of disturbances (such as UWB structures) makes TL simple assumptions not applicable for a undeniable variety of functions. within the final decade or so, the generalization of classical TL thought take into consideration excessive frequency results has emerged as a major subject of research in electromagnetic compatibility. This attempt led to the elaboration of
the so-called "generalized" or "full-wave" TL conception, which contains excessive frequency radiation results, whereas maintaining the relative simplicity of TL equations.

This booklet is geared up in major components. half I provides consolidated
knowledge of classical transmission line thought and different
field-to-transmission line coupling versions. half II provides different
approaches constructed to generalize TL idea.
