In this paper, the Fock current from the 3-D convex cylinder is considered. By using the incremental length diffraction coefficient technique (ILDC), the resultant high frequency scattered fields are expressed in terms of the Fock current from convex scatterer. To efficiently solve the scattered fields, we propose the efficient NSDP method. Numerical examples from the convex cylinder scatterer illustrate that the proposed NSDP method for calculating the high frequency scattered fields could achieve the frequency independent computational workload and error controllable accuracy.

In this paper, we first consider the Fock current from the 3-D convex cylinder. Next, on invoking the incremental length diffraction technique (ILDC), the resultant high frequency scattered fields are expressed in terms of the Fock current. We propose the NSDP method to calculate these scattered fields. Numerical examples illustrate that the proposed NSDP method for calculating the high frequency scattered fields could achieve the frequency independent computational workload and error controllable accuracy.
