Multi-Mode Analysis of Scattering by Bodies of Revolutions via the Combined-Field Integral Equation

“…To this end, the surface currents over the generating curves are discretized with piece-wise constant and piece-wise linear functions in the φ direction and the direction tangential to the generating curve, respectively. Other technical details regarding the implementation of the EFIE and MFIE, and the handling of singularities in the corresponding MGFs can be found in [12], [19].…”

“…The kernels of Z MF IE and Z EF IE are known as the modal Green functions, corresponding to the MFIE and the EFIE, respectively. For the MFIE and EFIE, the MGFs are given by [1], [19], [26] g…”

“…The scattering by such kinds of symmetric objects, also called bodies of revolution (BORs), are often characterized using integral equations, which are derived based on the boundary conditions applied to the electromagnetic fields at the surface of the BOR. Depending on whether electric or magnetic fields are employed in the formulation, these integral equations can be categorized into two classes: based on the electric field integral equation (EFIE) [8], [9], [10], [11], [12], [13] and based on the magnetic field integral equation (MFIE) [14], [15], [16], [17], [18], [19].…”

“…For the modest cases, we compare the results with those available in the literature. Not only does this article offer a direct solution for the computation of the modal Green functions (distinct from the singularity extraction methods [7], [19], [26]), but also it extends the EFIE recurrence relation in [27] to the MFIE case with an enhanced computational speed.…”
