Oblique Scattering From Radially Inhomogeneous Bianisotropic Cylindrical Structures Analyzed Using a Highly Accurate Volterra Integral Equation Approach

We study the oblique scattering of arbitrarily polarized plane waves from radially inhomogeneous and bianisotropic cylinders in the general case where all the elements of the four constitutive tensors are nonzero. The analysis relies on an exact reformulation of Maxwell’s equations as a second-kind linear Volterra matrix integral equation. The discretization scheme uses a high order, entire-domain, Nystrom method that employs the Gauss–Legendre–Radau quadrature. The entries of the Nystrom matrix have simple closed-form expressions. The proposed algorithms have exponential convergence and can handle both single-layer and multilayer cylinders with either continuous or sectionally continuous inhomogeneity profiles.
