In this research, the time-domain uniform asymptotic solution for the scattered field by a cylindrically curved conducting open surface was derived. The time-domain uniform asymptotic solution consists of the edge diffracted rays, the surface diffracted rays, the geometrical rays, the whispering gallery (WG) mode radiation field, and the combination of these waves. Comparisons of the time-domain uniform asymptotic solution with the reference solution calculated numerically from the combination of the frequency-domain numerical solution by the method of moment and fast Fourier transform (FFT) code confirm the validity and utility of the proposed time-domain uniform asymptotic solution
