Abstract

A time-domain (TD) asymptotic-numerical solution (TD-ANS) for a transient scattered field, which is a useful new reference solution on engineering applications, is developed for a two-dimensional transient scattered field from a cylindrically curved conducting open sheet excited by an ultra-wideband (UWB) pulse wave. The TD-ANS is represented by a combination of pulse wave elements; each element is obtained from a numerical integration. The TD-ANS is highly accurate and is useful in understanding transient scattering phenomena. The computation rate of the TD-ANS is very fast compared with that of a reference solution. The validity and usefulness of the proposed TD-ANS are confirmed by comparing with a reference solution and experimental-numerical results.
