Modular emulators of memristors and other higher-order elements from Chua’s periodical table

The paper presents a set of black-box modules for emulating higher-order elements (HOEs) from Chuás periodical table, based on special mutators. For the emulation of arbitrary HOE, four kinds of modules with various directions of movement across the table are necessary: one for horizontal direction, one for vertical direction, and two for diagonal directions. Another four mutators are needed in order to overcome the potential conflict of ideal sources if the same types are connected together. Overall eight kinds of modules are used. Their proper cascade connection can serve for emulating arbitrary elements from Chua's table.
