The Vagarious Dispersive Behavior in a Magnetically Uniaxial Metamaterial around the Plasma Frequency

摘要

We investigate the dispersive behavior around the plasma frequency in a magnetically uniaxial metamaterial. We show by theoretical analysis, numerical calculation and simulation that when material loss is considered and the EM wave is oblique incidence, the negative refraction of energy and the negative group velocity of electromagnetic wave will be observed with little losses. Since the proposed magnetically uniaxial metamaterial can be constructed in the GHz frequency easily, the abnormal refraction and group velocity will be experimentally validated in the future.
