Transverse waves are not the only energy that makes up each electromagnetic field.  There is also a part of the field called the scalar component, also called a longitudinal wave.

Scalar energy is considered, by the relatively few who know it exists, as potentially the greatest discovery in the history of science.  Scalar fields exist as the informational/non-physical component of all matter, but in this article we will be discussing them mainly in relation to electromagnetic fields (EMFs).
