Negative inductors and capacitors for SPICE simulation

It is explained that to simulate circuits containing negative inductances and capacitances using general-purpose simulators like SPICE, the networks under consideration must be transformed into suitable SPICE-compatible circuits. Criteria that the portion of the network containing the negative elements should meet are given. The SPICE network realizing these elements, when L and C are independent of frequency and time, is shown. An example of a Brune network is given.<
