Negative Effective Permeability Material Composed of Multi-Layer Ceramic Capacitors

Multi-layer ceramic capacitors (MLCCs) have been employed for miniaturizing the unit cell structure of metamaterials. In addition, specific absorption rate suppression methods and thin wave absorbers based on metamaterials composed of MLCCs have been reported. This paper proposes a negative effective permeability material composed of MLCCs. Firstly, effective permittivity and permeability are obtained from simulated S-parameters and compared with the dispersion characteristics. Next, the reflection S₁₁and transmission S₂₁characteristics of the stacked metamaterial structure composed of the MLCCs are analyzed and then compared with experimental results.
