Ferrite-based Magnetically Tunable Electric Metamaterial

摘要：

We experimentally demonstrate a magnetically tunable electrically resonant metamaterial (EMM) at microwave frequencies by introducing microwave ferrite rods into the periodic array of electrically resonant element. This tunability is based on a mechanism of magnetically tuning the inductance of resonant element via the active ambient effective permeability. It reveals that, by applying magnetic fields from 0 to 5000 Oe,resonance frequency of the EMM can be continuously and reversibly tuned in a range of about 800 MHz.
