Numerical Methods for Solving the Problem of Electromagnetic Scattering by a Thin Finite Conducting Wire

Electromagnetic scattering and absorption by randomly oriented fibers

“…Fiber's simple one-dimensionality and efficiency as electromagnetic obscurants draw attention for many applications. The theory of electromagnetic scattering and absorption by a fixed orientation fiber has been addressed both analytically [1] and numerically [2,3]. Experimental verifications of the theory in the long and short wavelength regions have been performed and published in the literature, where the key parameters of the theory have been tested through the extinction (or its components, scattering and absorption) and radar cross sections [4][5][6][7][8][9][10].…”

“…The calculations using Eq. (1) have been implemented in our published fixed orientation computational code, and extensive calculations have been done [2]. The fixed orientation code for single angles has been available since the referenced paper was published [2].…”

“…(1) have been implemented in our published fixed orientation computational code, and extensive calculations have been done [2]. The fixed orientation code for single angles has been available since the referenced paper was published [2]. A new version of the code that computes the orientation average for the cross sections has been developed, and the results of the study are summarized below.…”

Design of Metaparticles as Sharp Frequency-Selective Obscurant Aerosols

“…(a) Proposed particle, (b) fabricated particle. the extinction cross section of a copper fiber with length 26 mm and diameter of 30 µm, with the E-field along the fiber axis [1,2,5]. The geometrical parameters of the fiber were chosen to produce the first resonant at 5.5 GHz.…”

“…A sharpedged transmission bandstop is in demand where excellent out of band transmission is desired. Metallic fiber -like particles are good candidates and have been studied extensively, both numerically and experimentally [1][2][3][4][5]. While fibrous aerosols are considered to be relatively sharp resonators, their behavior is not as sharp as desired.…”
