Introduction

This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book serves as a monograph in the relatively new and underdocumented field that we call STatistical ElectroMagnetics. It considers the shape and frequency separation of the resonances of the enclosure, and evaluates how energy is statistically distributed among these resonances. The book documents studies, by us and others, to understand and model statistically the ElectroMagnetic (EM) field and cable response of an enclosed asset and its wiring during High-Power Microwave attack or in the presence of other threatening Radio Frequency leakage and penetration. It provides a basic tutorial on probability, starting with fundamental concepts such as mean, variance, correlation, covariance, independence, and skewness. The chapter illustrates how to create EM field drivers to couple to the wiring harness, where these fields have any desired statistical distribution and also possess local autocorrelation or coherence with respect to small shifts in position or frequency.
