Electric megahertz metamaterials designed with deep subwavelength multilayered meander line resonators

摘要

Electric megahertz (MHz) metamaterials are designed and numerically demonstrated with multilayered meander line (MML) resonators in deep subwavelength. The MML resonator is featured with a large intrinsic inductance and adapted to operate at a very low frequency. To study the conceptual resonator, an equivalent circuit model is built. Closed forms are given to predict the effective metamaterial characteristics, which are subsequently validated in full wave calculations. A proof-of-concept 7-layer MML resonator is demonstrated working at 84.1 MHz. The element size is 1/178.. Strong electric resonance and negative permittivity are observed in the MHz spectrum.
