Abstract

Spatiotemporal variation of material parameters (capacity and conductivity) can lead to unconventional diffusion phenomena. We have constructed and tested a metamaterial consisting of spatiotemporally variable capacitors and switches, demonstrating highly asymmetric charge diffusion and accumulation.
