General Non-Radiating Networks

Complex feed networks can be simplified by including them as a circuit representation using general network blocks.

General networks (defined using network parameter matrices) can be used to model a feed network. These non-radiating networks may be interconnected (cascaded) and excited or loaded directly at the ports.

The voltages and currents at the ports of these ideal representations of networks may interact with currents and voltages on parts of the model that are solved using other solution methods, though no radiation-based coupling is taken into account.
