“…For example, in [9], [10], three methods of obtaining the channel impedance are given: transmission-line model, dipole model with assumed sinusoidal current distribution, and a model based on a two-dimensional time-domain finite-difference approach.…”

“…The method was onginally developed by Bennet and Weeks [14] and the time-domain equation 1 aa(r', r) X t 3R da . ceo ar R3 (10) This is an integral equation in the related unknowns J3(/, r) and a(ri r) and is commonly called the Electric-Field Integral Equation (EFIE). It is the time-domain form of the EFIE.…”

“…These developments include the use of advanced composite materials which provide less electromagnetic shielding than conventional metallic structures, the increased use of low-level semiconductor circuits in many mission-critical subsystems, and the trend toward completely fly-by-wire aircraft. In addition, recent data describing the lightning environment has shown that the environment has a much larger content in the aircraft resonant regions (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) [1] - [4] than was previously thought [5]. The result is that the lightning/aircraft electromagnetic interaction problem needs to be re-examined.…”

The electromagnetic interaction of lightning with aircraft is a complex event. Because of new aircraft technologies, it is becoming more important to be able to predict and understand lightning-induced transients on avionics systems. In this paper, a review of state of the art of lightning-interaction modeling is presented. The overall interaction process is discussed, and specific modeling techniques are given for external interaction, internal interaction, and internal propagation. Some examples are given for lightning strokes attached to an aircraft. A discussion of nonlinear effects is also given, and comparison between nuclear electromagnetic pulse and lightning environments are presented. Finally, an overview of hardening techniques is given. An extensive bibliography is included.
