  1. \({\,}^\S \)The value at the reference Point 4 is normalized to 0 dB in each pathway.
  2. \({\,}^\ddag \)The insertion loss (dB) incurred at the Junctions is determined by subtracting the E-field power at the 90\(^\circ \)-bend to that at Points D5/U5 located at exits of the reconfigurable T-junction.
