This research study presents a new methodology for area-efficient, low-complex multiplexer designs using dipole coupling. Our approach uses micro-magnetic simulation to model 2D device structures of ferromagnetic and antiferromagnetic coupled nanomagnets. The designed multiplexers are reconfigured at run-time by applying varied external magnetic flux densities. It also provides run-time reconfigurability and reduces the number of physical designs needed to achieve all truth table entries. We used driver and slant edge nanomagnets of varied sizes for inputs. The proposed layout designs are verified using the MuMax3 micro-magnetic simulation tool. The slant edge nanomagnets-based design exhibits 88% and 86% reduction in the number of nanomagnets and area occupancy respectively compared to the state-of-art design.
