▎ 摘  要

We study ballistic transport in periodically gated bilayer graphene as a candidate for a two-dimensional electronic metamaterial. Our calculations use the equilibrium Green's-function formalism and take into account quantum corrections to charge density changes induced by a periodically modulated top-gate voltage. Our results reveal an intriguing interferencelike pattern, similar to that of a Fabry-Perot interferometer, in the resistance map as a function of the voltage V-BG applied to the extended bottom gate and V-TG applied to the periodic top gate.
