The inductor and capacitor are the only circuit elements which need a more involved treatment in the MD case. The capacitor is treated as the dual to the inductor, replacing by and by , and needs no further comment, other than that, as with the lumped capacitor, there is no sign inversion in the resulting MD wave one-port. The graphical representations of these MD one-ports and their MDWD equivalents are shown in Figure 3.5. Note that for the sake of compactness, in the circuit diagrams that will follow, we will use the derivative notation of the MDWDF literature  where we have
All the other elements for which we will have a use, namely the resistor, transformer and gyrator, as well as scattering junctions are memoryless and hence their pointwise behavior in MD is identical to that of their lumped counterparts. Their graphical representations are also identical (see §2.2.4). We must keep in mind however, that these are still distributed elements. For example, a resistor of resistance in an MDKC represents some resistivity at every point in the domain of the problem.
A network made up of Kirchoff connections of -ports which are individually MD-passive can be shown (through the use of Tellegen's Theorem , which is unchanged in multiple dimensions) to be be MD-passive as a whole .
