  5. Abstract: FEKO is based on the accurate Method of Moments technique. The MoM, which scales poorly with frequency, has been hybridised with two asymptotic high frequency techniques namely: physical optics (PO) and uniform theory of diffraction (UTD). This hybridisation enables the solution of much larger (in terms of wavelengths) problems. The implementation and validation of the hybrid approach provides major computational advantages for various classes of electromagnetic problems. Furthermore, the accuracy of the PO approximation can be improved by correction terms for edges and wedges, or by applying Fock-currents to account for creeping waves on convex structures. MoM extended to handle multiple homogeneous dielectric bodies, dielectric coated wires, thin dielectric sheets. Special Green's functions are used for analysis of multilayered structures. Very efficient parallel processing as well as out of core matrix solution techniques. Parametric optimisation and CAD interface available.
