Negative effective permeability metamaterial using multi-layer ceramic capacitors

摘要

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 metamaterial using MLCCs. Firstly, the effective permittivity and permeability of the unit cell are obtained from simulated S -parameters and compared with the dispersion characteristics. Next, transmission S _(21) characteristic of the stacked metamaterial structure composed of the MLCCs is analyzed and then compared with the measurement result.
