The fast solver for calculating the high frequency scattered field from the Fock current on the surface of the 3-D convex scatterer

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.
