“…A negative refractive index was obtained on a circular design in a previous study [13], [22]. Loop surface current existing in the surface of the circular shape produces the magnetization phenomenon, the presence of which is indicated by the permeability of the sample.…”

This study aims to use the hand-painting method in designing and fabricating a metamaterial based on a circular shape that exhibits a negative refractive index over the microwave spectrum. Hand painting is a simple and inexpensive fabrication method. This study applies silver ink as a periodic conductor to glossy paper as the dielectric substrate. The spectrum of investigation in this study is 3–6 GHz, and the experimental results obtained are compared with the simulation results. The slight error obtained between transmission results from the simulation and the experiments reflects limitations in the fabrication methods used. Overall, the experimental results present good agreement with the simulation results. The electrical properties of the metamaterial are retrieved from the transmission and reflection simulation results. The simulation results are employed instead of the experimental results because of the fluctuating data provided by the latter. The refractive index presents a negative value at 3–3.6 GHz.

“…The unique and exotic behaviors of the layered metamaterials are created by the electromagnetic properties that are specifically chosen for each layer. Like other metamaterials, layered metamaterials can also exhibit extraordinary electromagnetic properties at a specified operation frequency, such as negative refractive index [6,7], near-zero permittivity or permeability [8,9], anisotropic behavior [10,11], and other unusual responses [12], by carefully designing the geometry, composition, and arrangement of the layers. More importantly, the layered metamaterials can be designed with a sophisticated microstructure to operate across a broad range of frequencies, e.g.…”

A precise one-to-one equivalent nanocircuit model for layered metamaterials is presented in this work. The theoretical analysis establishes a precise link between the nanocircuit system and the optical ﬁlm system by comparing between the optical transfer matrix of an optical ﬁlm and the transmission matrix of the distributed-element model. Through dimensional analysis, the connection between the optical properties of the ﬁlm and the distributed circuit components of the transmission line is revealed. Subsequently, the lumped-element model is simpliﬁed to the distributed-element model for nonmagnetic ﬁlms with diﬀerent optical features. Finally, the lumped-element model is further applied to multilayer metamaterials with diﬀerent microstructures. All analysis is conﬁrmed through the agreement between the S-parameters of the equivalent nanocircuit model and the reﬂection and transmission coeﬃcients of the layered metamaterials.

“…Metasurfaces are arrays of artificial subwavelength nanostructures that can localize the electromagnetic (EM) fields at the nanoscale or manipulate the far-field scattering, which can realize a variety of novel physical properties, such as negative refractive index [1,2], near-zero refractive index [3], abnormal reflection and transmission [4,5], and Fano resonance. The Fano resonance originates from the destructive interference between the bright and dark modes excited in the near-field [6][7][8][9], which can give rise to huge field enhancement and sharp resonant profiles with high Q factors.…”

In this paper, we design and theoretically investigate a silicon notched disk metasurface-waveguide (NDMW) system, realizing a new approach to excite Fano resonance by introducing a waveguide layer to generate quasi-guided mode (QGMs) resonances. By comparing the transmission characteristics of the silicon complete disk metasurface (CDM), the silicon complete disk metasurface-waveguide (CDMW) system, and the NDMW system, the formation mechanism of Fano resonances in multiple different excitation modes is analyzed. Furthermore, the Fano resonance characteristics of the NDMW system for different polarization conditions are studied. It can be found that different polarization states can excite different multiple Fano resonances in the NDMW system. Finally, the effects of various structural parameters on the multiple Fano resonances characteristics are investigated. Utilizing the narrow linewidth and significant near-field confinement of the Fano resonances, an optical refractive index sensor can be obtained with the sensitivity of 113 nm/RIU and the maximum quality (Q) factor of 2*10^5 . The proposed system opens up an avenue to develop high-performance biological sensors.
