Asymptotic Analysis for Transient Scattered Electric Field from a Conducting Cylinder Coated with a Thin Dielectric Layer

By applying the Fourier transform method to each transient scattered electric field element represented by an integral form, we derive time-domain asymptotic solutions (TDASs) when a high-frequency pulse wave is incident on a two-dimensional conducting cylinder coated with a dielectric layer (2-D coated conducting cylinder). We assume that the radius of a coated conducting cylinder is sufficiently large as compared with the wavelength of a central angular frequency of a pulse source function and that a coating layer is thinner than the wavelength.
