Nonlinearly loaded multiport structures have promising features for the application of controlling scattered fields. Modelling such structures can lead to investigations up to hundreds or even thousands of ports, which poses a challenge to full-wave simulation techniques. In order to identify limitations for large scale problems, a hybrid simulation method using macromodeling and recursive convolution is adopted due to its scalability. A numerical complexity analysis is carried out for the extraction of frequency data, macromodeling of the network parameters and computation of transient responses. Of particular interest are the number of ports, load types, wave excitations and field probes. Bottlenecks are identified and possible improvements of the adopted method are proposed.
