The $RCWAxnode command is used to define the position of boundary point in each layer which assigned in [[$RCWAxdiv]]. It also needs to goes with the [[$RCWAxdiv]] and [[$RCWAperiod]] to define number of boundary point and the period of simulation domain. The left boundary point does not need to assign which automatically set as -2/period.
