Recent research including Cluster Postdoctoral Researchers Yi Chen and Ke Wang and Principal Investigator Martin Wegener has shown that electrical conduction in specially designed metawires fundamentally differs from Ohm’s law. Unlike conventional conductors, where resistance increases linearly with length, meta-wire resistance shows oscillatory behavior due to nonlocal conduction effects. This phenomenon results from countercurrents flowing against the applied electric field, leading to wave-like resistance patterns that can be controlled by structural design. These findings open up new possibilities for remote electrical sensing, heat conduction, and particle diffusion.
