Abstract:
The analysis of the transient response of a five-wire planar array of identical thin wire scatterers is presented. The transient current induced on the individual wires comprising the array exhibits inherent intermodulation effects. This particular effect is explained in terms of the excitation of several of the natural frequencies obtained by applying the singularity expansion method (SEM) to the multiple-wire arrays. The natural frequencies group themselves into layers that can each be associated with the natural singularities of the isolated thin-wire scatterers, that constitute the individual elements in the array. Calculation of the coupling coefficients associated with the natural modes corresponding to the natural frequencies illustrates the manner in which different intermodulation frequencies appear in the transient response of the array as a function of the excitation orientation and polarization. Tables and curves illustrating the pertinent parameters determining these intermodulation effects are presented for one-, two-, three-, four-, and five-wire arrays
