Electromagnetic scattering of tubular cylindrical structure  Double series formulation and some results
Abstract
Depending on its lengthtodiameter ratio, the tubular cylindrical structure can represent either a tubular cylinder or a strip loop. The problem of electromagnetic scattering from such a structure is studied. Chebyshev polynomials are used to represent the axial dependence of the surface current distribution. Formulation is derived for solving the expansion coefficients of the current distribution. Since the double series expansion coefficients of the Green's function over such a basis are known, no numerical integration is required under this formalism. The theory is applied to compute the backscattering cross section of a tubular cylinder over a range of frequencies. The theoretical results agree with experimental data.
