Moment-method analysis of circularly symmetric reflectors using bandlimited basis functions

To reduce the computational requirements, a quasilocalised, spatially bandlimited set of basis functions is adapted and explored in the context of the moment-method (MM) analysis of circularly symmetric reflectors. By considering the analysis of representative geometries, its performance is evaluated against results produced by entire-domain and local-domain basis functions. It is shown that the use of bandlimited functions is particularly useful in this context, improving the computational efficiency in terms of both storage and CPU time requirements
