3D stand-up metamaterials with a purely magnetic resonance at terahertz frequencies
In this paper we present a copper-based 3-dimensional (3D) stand-up metamaterial which displays a purely magnetic resonance at terahertz (THz) frequencies. A multilayer-electroplating technique is used to fabricate these arrayed structures and experimental results demonstrate a strong LC resonance at 1.38 THz with quality factor of 18.7. The successful design, fabrication and characterization of these 3D structures provides a new pathway for implementing novel electromagnetic properties at terahertz frequencies.
In this paper, a modeling and simulation method for planar interdigitated ruthenium oxide MEMS supercapacitor was proposed based on the electrochemical reaction mechanism of supercapacitor. The study simulated the planar interdigitated ruthenium oxide MEMS super capacitor using Comsol software. The highly accurate charge and discharge curves of the super capacitor, electric potential distribution graph and the concentration distribution graph were got through simulation. The effects of two structure-parameters were discussed in the research.
