… Therefore, MIMO antennas can accomplish high isolation by … that the bandwidth, size, and
isolation cannot be well balanced in a … , and high isolation characteristics of the antenna. …

… strips to generate negative permittivity, a negative index of refraction that is matched to free
… to verify the left-handed behavior with an extracted index of refraction of $-$1.04 matched to …

… We also wish to stress that this seismic metamaterial does not exhibit a “negative refraction
index.” Rather, the effective mass depends on the frequency and becomes negative for …

… In this article, a high-isolation resistor-less MWPD based on metamaterial structures is … the
proposed metamaterial unit cells between two dielectric layers resulted in an isolation of about …

… The methodology applied in this study could be applied to structures to design high-refractive-index
metamaterials at multifrequency. Since polyimide has good flexibility and isolation …
