Radiation and scattering by thin-wire structures in a homogeneous conducting medium

Fourier Transform Application in the Computation of Lightning Electromagnetic Field

“…Fourier transform of the channel-base current is also necessary if calculating equivalent voltage source as a product of the input impedance and the channel-base current in frequency domain (Moini et al 2000, Shoory et al 2005, instead of the current source itself at the channel-base. A few computer programs for antenna analysis are used for calculations (Richmond, 1974(Richmond, , 1992Bewensee, 1978;Burke & Poggio, 1980Djordjevic et al, 2002), and most of these use the voltage generator as excitation (Grcev et al, 2003). Real and imaginary parts of FFT in the frequency range fє [-200∆f ,+200∆f] are presented in Figs. 11 and 12.…”

On the radial component of the electric field for a monopole phased array antenna focused in the near zone

“…The moment method mutual impedance matrix is evaluated by using computer subroutines developed in Richmond, 1974 [171.…”

Bistatic Radar Cross Section of a Perfectly Conducting Rhombus-Shaped Flat Plate

“…For all the bistatic angles, when the plate is not tilted the simulated cross-polarized RCS is very low, and so the measurements are dominated by isolation/clutterinduced errors. These cross-polarized data appear in [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], and 3-26 and will not be discussed further.…”
