COMPUTATION OF PULSED ELECTROMATGNETIC FIELDS: WITH NEURAL NETWORK APPLICATIONS

This chapter provides an integral method and the finite element method for transient field computation after reviewing the basic concepts involved and the simple transient current models for frequently encountered sources. It provides a detailed discussion of time-domain analysis using both the integration scheme and the mode representation scheme. The chapter analyzes the stability of the differential equations and the numerical methods that are most commonly used. It also discusses some important features related to the development of general computer programs for a variety of engineering electromagnetics problems. The computation of pulsed electromagnetic pulses is essential in the analysis and design of a large number of devices and systems. The response of high temperature plasma to laser pulses is important in thermonuclear fusion experiments for bringing particles close together by implosion. Knowledge of lightning and nuclear electromagnetic pulses is critical in designing stable control systems and protection for fly-by-wire aircraft.
