The absolute or free-field gain of a simple antenna can be approximated using standard antenna theory formulae or for a more accurate prediction, numerical methods may be employed to solve for antenna parameters including gain. Both of these methods

In implementing electromagnetic vulnerability (EMV) testing on operational helicopters flelding a variety of avionic, communication, and weapons systems, the testing levels as spelled out in MIL-STD-464A require most test labs to position the high po

An analytically tractable model is proposed in this initial study of the electromagnetic phenomena that control our ability to synthesize, by using a near-field source, the effect of plane-wave coupling through an aperture into the interior of a vehi

The late-time field scattered from an arbitrary wire structure is formulated in terms of the singularity expansion method (SEM), and the contribution of each mode is shown to be representable as the product of two coupling coefficients. One coefficie

A modal radar cross section (RCS) of arbitrary wire scatterers is constructed in terms of singularity expansion method parameters. Numerical results are presented for both straight and L-shaped wire targets and are compared to computations performed

A surface impedance function (SIF) appropriate for use on the aperture surface of a conducting body with a dielectric-filled cavity, is presented. Unlike the usual SIFs that might be used on an aperture, this SIF takes into account not only the wave

Transverse electric (TE) and transverse magnetic (TM) scattering from dielectric-filled, cavity-backed apertures in two-dimensional bodies are treated using the method of moments technique to solve a set of combined-field integral equations for the e

The complex plane natural resonances for several perfectly conducting bodies of revolution (sphere, right circular cylinder, prolate spheroid, and circular disk) are calculated using electric, magnetic, and combined field integral equation formulatio
