This arrangement is the dual to the previous case. We now set

and

We then have

for half-integer and . It is rather interesting that in (2+1)D, if we have and , this arrangement (and not that of type I) allows the series junctions to be treated as throughs (with sign inversion). We may thus operate at a reduced sample rate in this case. This particular choice of immittances, in the constant-coefficient, lossless and source-free case with , yields the original form of the waveguide mesh proposed in [198], and mentioned in §4.2.7. We also note that networks such as this and type I, for which the connecting immittances may vary spatially have also been explored in TLM [29,159].
