A novel equivalent circuit for the fishnet metamaterial structure is presented. Using the Rotated Transmission-Line Matrix (RTLM) method, the equivalent circuit of a three-dimensional metamaterial structure is obtained. By firstly employing the circuit model of the multi-resonance hybrid coupled filter, the RTLM equivalent circuit can be well analyzed and used to design high-performance fishnet metamaterial...
A novel three-dimensional LC-based metamaterial topology to model traditional fishnet structure is proposed. Rotated Transmission-Line Matrix (RTLM) unit as one independent half cell from the typical Transmission-Line Matrix (TLM) unit with each incident polarization rotated by 45°, is supposed to save the computation time and decrease the processing data when a structure is analyzed, especially when...
Fishnet metamaterials consist of two or more conducting fishnet layers separated by homogeneous dielectric layers. Different from other planar multilayer metamaterial structures fishnet metamaterials do not require vias for through-contacting between the layers. This allows low-cost production of three-dimensional metamaterials by spray coating with organic (carbon nanotubes CNTs) or metallic (silver)...
A possible way for the economic production of three-dimensional metamaterials is based on the use of planar multilayer structures. The fabrication of two-dimensional metamaterial structures will be performed by spray coating with organic (carbon nanotubes) or metallic (silver) nano pigment inks. Organic materials allow to adjust the area resistance of the conductive layers for optimum broad-band design...
A novel frequency diplexer was proposed in this paper, based on the integration of a SIW- CSRR bandpass filter and SIW highpass filter. SIW has the highpass characteristic as RW; CSRR is the image of SRR and takes some metamaterial features. A SIW-CSRR bandpass filter is firstly designed, and then a simple SIW highpass filter. The combination of these two filters thus leads to a simple and compact...
