Memristive two-ports

In the paper, the memristive two-port is defined via its constitutive relation as a two-dimensional surface in a four-dimensional space of the port charges and fluxes. It follows from six possible representations of this two-port that it can be modeled via classical two-terminal memristors/memductors, complemented by four types of memristive controlled sources, each of them being controlled by two state variables. Two examples of the memristive two-port are analyzed, viz. the circuit with mutual memristors and the memristive transformer.
