摘要

利用相位展开法从复散射参数中准确地提取了9-12 GHz频率范围内折射率为负的超材料平板的本构参数。这种技术依赖于在复杂透射系数的相位上适当地添加一个由透射系数的相位达到可见π的共振频率构成的阶梯函数。

Unambiguous determination of constitutive parameters of a metamaterial slab

The constitutive parameters of a metamaterial slab showing negative refractive index over the 9–12 GHz frequency range are unambiguously retrieved from complex scattering parameters upon using the phase unwrapping method. Such a technique relies on properly adding to the phase of the complex transmission coefficient a stepwise function constructed from the resonance frequencies at which the phase of the transmission coefficient reaches ∓ π.
