The implementation of the Foster's model in the fREEDA circuit simulator is reported and the modeling of a two-port coupled inductor is presented as an example.}, number={9}, journal={IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES}, author={Mohan, R and Choi, MJ and Mick, SE and Hart, FP and Chandrasekar, K and Cangellaris, AC and Franzon, PD and Steer, MB}, year={2004}, month={Sep}, pages={2207–2214} }
