Novel Time-Domain Uniform Asymptotic Solution for Transient Scattered Field

Novel time-domain uniform asymptotic solution (novel TD-UAS) for transient scattered field excited by a cylindrically curved conducting open surface with a constant radius of curvature is presented in this paper. We shall derive the novel TD-UAS, which is applicable in the transition regions including the reflection boundary and the shadow boundary, by applying only the Fourier transform method. The accuracy and the validity of the novel TD-UAS are confirmed by comparing both with the reference solution calculated numerically from the combination of the method of moment and the FFT numerical code and with the hybrid experimental-numerical results obtained from the combination of the experimental results for the frequency-domain scattered field and the FFT numerical code.
