Asymptotic solution for transient scattered field by a cylindrically curved conducting surface

We have derived the time-domain asymptotic solution for the transient scattered field by the cylindrically curved conducting surface by extending the corresponding frequency-domain asymptotic solution. The validity and utility of the time-domain asymptotic solution derived here have been confirmed by comparing with the reference solution. We have shown that the time-domain asymptotic solution, which is represented by the summation of each pulse element, is easy to understand the physical insight of the scattering phenomena by the cylindrically curved conducting surface.
