Solution of electrically large scattering problems on a laptop

We consider the application of full-wave methods to electrically large structures with emphasis on an implementation that allows modest computing resources to be used even for very large problems. First, we highlight the recent development of a Multi-level Fast Multipole Method (MLFMM) implementation based on Higher-Order (HO) basis functions, which allow significant time and memory reductions as compared to previous MLFMM implementations. Second, we show how the use of the harddisk for some of the more memory demanding components in MLFMM can allow us to solve much larger problems than the memory of the computing platform makes room for, with only a modest increase in computational time.
