Design of a new wide-angle polymer X-junction

We report the theoretical performance of a digital switch based on a wide-angle, low-loss asymmetric X-junction we recently proposed. At a full-branching angle of 1.2 degrees, the cross-talk and transmission at the zero-voltage state have been -20 and -0.5 dB, respectively. In the switched state, they are -19.5 and -1.1 dB, respectively.
