Correction to: Current inverting metamutator, its implementation with a new single active device and applications

Abstract

Voltage Inverting Metamutator (VIM) and Current Inverting Metamutator (CIM) recently introduced in [1] were defined, respectively, with polarities shown in Fig. 1 and relations (1) and (2). However, a careful examination reveals that there is no difference between VIM and CIM of Fig. 1b as changing the reference directions of v n and i n in VIM gives CIM as shown in Figs. 1b and 2. So the 4-ports in Fig. 1a, b are the same. The CIM as given by Fig. 2, with the same reference directions as those of VIM, and defining relation (2) is an entirely different 4-port. In fact, their circuit level realizations are respectively given in Fig. 3a, b.
