Caculation of Diffraction Field of Creeping Waves on Arbitrary Convex Surface Based on Non-uniform FOCK Currents

This paper researched the non-uniform diffraction currents (NU currents) on a cylinder and calculated its radiation field using the theory of incremental length diffraction coefficients (ILDCs). Afterwards, we extended this method to arbitrary convex surface, for calculation of complex integral contain high-oscillation characteristic of the phase, this oscillation can be eliminated by introducing the phase-unwrap technique. At last, an example of an arbitrary convex surface scatterer illustrated the universality and accuracy of the method in this paper.
