【 摘 要 】

References(12)We derive a time-domain (TD) asymptotic-numerical solution for the transient scattered electric field by a coated conducting cylinder covered with a thin lossy dielectric material by substituting the frequency-domain asymptotic solution into the transient scattered electric field integral. The TD asymptotic-numerical solution is represented by a combination of each transient scattered field element which is obtained from the numerical integration. The validity and computational efficiency of the TD asymptotic-numerical solution are confirmed by comparing with the reference solution. We show that, since the TD asymptotic-numerical solution can extract and observe each pulse wave element from the response waveform even when the pulse wave elements overlap mutually, it is effective understanding the scattering phenomena in detail.
