The interaction between two nanowire cross-junctions is studied in a three-wire double-junction structure. The dc conductances between terminals in the double-junction structure are calculated from the Green's function, which is obtained using the modular Green's function approach. Significant oscillations are found in the inter-wire conductances in both junctions, which are the consequence of interference of electron waves reflected between junctions. A phenomenological expression, which can relate the positions of neighboring oscillation peaks, is developed based on the interference mechanism. The interaction between quasi-bound states formed at the junctions is found to be negligible and has no significant effect on the inter-wire conductance peaks. Our results show that interaction between neighboring junctions should be properly considered in the modeling and design of nanowire devices and circuits.
