Analysis of electromagnetic field diffraction by bodies of revolution with the use of the modified method of discrete sources

Two approaches to the solution of the problem of diffraction by a plane grating of dielectric bodies of revolution

“…OF INTEGRAL EQUATIONS We solve the formulated problem using the auxil iary current method that hereinafter is reduced to the MMDS [1][2][3][4][5][6]. To this end, we represent the wave field outside the region of the grating and inside the central elements of the grating as …”

“…Next, substituting formulas (46)-(48) into surface equation system (23), (24), we come to the following infinite system of 1D integral equations The method of calculation of quantities is described in [1][2][3].…”

“…System (49), (50) is again reduced to an algebraic system using the collocation method [1][2][3][4][5][6]. Colloca tion points β n (or ring source points [8]) are chosen according to the first relation in formulas (31).…”

“…This problem is rather complicated to be realized numerically because the geometry has no axial symmetry. The problem is solved here using the modified method of discrete sources (MMDS) [1][2][3][4][5][6]. The close problem of diffraction of a plane wave by a plane grating of impedance bodies of revolution was earlier considered in [4].…”
