Electromagnetic scattering by a conducting cylinder coatedwith a uniaxial chiral layer of varying thickness: generalized mode-matching method Original Research Article

Based on the concept of characteristic waves and the method of angular spectral expansion, cylindrical vector wave functions are developed to represent the electromagnetic waves in a uniaxial chiral medium. To illustrate how to use the present cylindrical vector wave functions in a practical way, a generalized mode-matching method is proposed to study the electromagnetic scattering of a conducting circular cylinder coated with a uniaxial chiral layer of varying thickness. The excellent convergence property of the bistatic echo width is numerically verified, which establishes the reliability and applicability of the present cylindrical vector wave functions and generalized mode-matching method for a two-dimensional problem with a curved surface coating of a uniaxial chiral medium.
