“…The proposed method has the potential to be used to develop coding or a reconfigurable metamaterial array due to its ability to arbitrarily distribute multiple materials. In the scenarios, there is no periodic arrangement but a regular arrangement of different materials, since the regular arrangement of materials is reconfigurable [30,31]. The proposed method can be used to fix one or few materials on the substrate first, and then deposit other materials to fill in the blank part of the substrate.…”

Terahertz (THZ) band stop filter can be used to filter interference signals in a filter pass band. The quality factor (Q) is the most important index to evaluate the transmission performance of filter. Usually, the high Q, the narrow bandwidth and the large slope of the stop band will promise the good filtering accuracy and transmission response. However, the Q value taken from metamaterial structures designed on the plane is always only in the single digit, resulting in less than satisfactory in filtering performance. Herein, a high Q terahertz band stop filter based on metamaterials was proposed. To fabricate this three-dimensional (3D) metamaterial structure, a microtopographic substrate guided method with feasible and high accuracy capacities was proposed. As a result, the device is measured to be in the filtering state in 1.038-1.102 THz while it is stopped in 1.062-1.066 THz. The similarity between the experimental and simulated transmission is up to 86.32%, indicating the fabricating method possesses a high accuracy. Accordingly, the Q value was calculated to be as high as 532. The band stop filter with this record Q value can be widely used in THZ detection, imaging and sensing in future. Meanwhile, the proposed fabrication method is effectively applied in 3D metamaterial and THZ device as well.

“…On the other hand, flexible material parameters and geometrical configuration of new chip technology can be utilized to tap the potential physical features of spoof SPPs. Recently, many works have been proposed to break the challenge of realization and application of spoof SPPs, including achieve efficient excitation using the characteristic impedance extraction method [377], reduce transmission loss using dispersion design [378] or loading parallel varactors in reconfigurable units [379], and replace fundamental channels in complex systems [311,312].…”

“…It is worth mention that the two steps may belong to a cyclic process, which means that the mapping step is supposed to be performed iteratively to ensure the effective and high-quality modulation and demodulation of spoof SPPs. In recent years, reconfigurable spoof SPPs [336,349,379] possessing dispersion tenability have attracted a lot [14,311,312,371,372,376]. Reproduced from [14].…”

“…Thus, there is a need for a more comprehensive method to be devised for obtaining the basic characteristics of these structures—such as the real and imaginary parts of the complex wave numbers of spoof plasmonic waves, and their impedance behaviors—regardless of the types and shapes of the structures. Recently, loss the analysis of reconfigurable spoof surface plasmon polaritons has also been done 18 . On the other hand, having a method that is independent of the shape of the unit cell and can also analyze reconfigurable SSPP structures is also useful.…”

In this paper, a semi-analytical approach is introduced to analyze a spoof plasmonic structure, with an arbitrary geometry. This approach is based on a combination of techniques that employ a full-wave simulator and the Bloch theorem. By applying periodic boundary conditions, the real and imaginary parts of the equation obtained from the equivalent network have been calculated. To show the accuracy and validity of this proposed approach, a complementary Minkowski fractal SSPP unit cell has been designed and analyzed, and this has been used in a surface plasmonic transmission line. The results of our proposed method have been compared to measured results, and the simulated and measured results showed that the SSPP transmission line possesses high performance, from 1.45 to 5 GHz.
