Abstract

We study the asymptotic analysis method for the magnetic-type (H-type) transient surface diffracted ray (transient SD) when an ultra-wideband (UWB) pulse wave is incident on one of the edges of a curved conducting surface. The time-domain (TD) asymptotic solution is derived by applying the saddle point technique to evaluate the H-type transient SD integral. The validity of the TD asymptotic solution proposed here is confirmed by comparing with both the reference solution calculated numerically and the conventional TD asymptotic solution.
