Fast inhomogeneous plane wave algorithm for scattering from PEC body of revolution

To solve large-scale electromagnetic scattering problems for bodies of revolution, a fast inhomogeneous plane wave algorithm (FIPWA) is developed. By using the Weyl identity and designing a proper integral path, the aggregation and disaggregation factors can be computed efficiently in FIPWA. Both the memory and CPU time requirements are significantly reduced for large scale BOR problems over the method of moments. Numerical results are given to demonstrate the validity and the efficiency of the FIPWA method to perfect conductors, but the method can be extended to dielectric BORs. © 2010 Wiley Periodicals, Inc.
