Figure 2e and f illustrates both reference
cases, A for s f 0 and B for s f ¥ respectively. Because of the
presence of numerous 90° angles in reference case A, the channel
width is multiplied by a x2 factor, which corresponds to an
effective cross section of 141 ím. For reference case B, the
effective width remains unchanged to 100 ím while the effective
length of the channel is enhanced by the same x2 factor (i.e. L
) 2828 ím). In addition, a third reference channel (reference case
C) featuring a width of 100 ím and length of 2000 ím is introduced
in the study.
