“…In most of the numerical methods, magnetized graphene is usually incorporated in the algorithm by transforming the surface conductivity to a volumetric conductivity by dividing the thickness of the graphene, which might introduce a multiscale computational problem in simulation, require massive CPU time and memory, and make the optimization process tiresome. In order to overcome this problem, the wave concept iterative process method can be applied by treating the 2D materials as conductive surface boundaries, to not only yield precision in the result, but also reduce the time consumption and memory size [16][17][18][19][20][21][22][23][24][25].…”

An effective and precise approach to the Wave Concept Iterative Process method modeling of magnetized graphene sheet as an anisotropic conductive surface is used to analyze the anisotropy of magnetostatically biased graphene and for studying an electrically doped magnetically biased graphene non-reciprocal antenna array for THz applications. The tuning of the performance of the array antenna is possible by varying the magnetic field and the chemical potential of graphene material. The return loss value decreases by increasing the magnetostatic bias and increases when the chemical potential increases.

This paper suggests a new miniaturized antenna for radio‐frequency identification (RFID) applications of 2.45 GHz. Our structure consists of a circular microstrip patch antenna which incorporates two concentric annular slots is printed on a multilayer substrates. The bandwidth, one of the most important characteristics of antenna, can be significantly improved by using a multilayer dielectric configuration. we aim by this study to show that the effect of radiating structure loaded by annular rings for the patch size reduction as well as the advantage of this structure being to create a circular polarisation in the direction of maximal radiation pattern. The wave concept iterative procedure is used to analyse this new antenna. Using the proposed procedure, less computing time and memory are needed to calculate the electromagnetic parameters of our design. The validation of the results of our developed model was verified with known commercial software called “CST Microwave Studio Software” followed by an experimental test. According to the reached results, we can judge that our new design antenna is suitable for RFID applications in the 2.45 GHz band.

“…One term represents the inter-band conductivity, and the other represents the intra-band term. The surface conductivity in the terahertz band can be expressed using only the first inter-band term and neglecting the second term in-band as it has no significant effect [19,20]. The surface conductivity is as follows The inter-band conductivity is…”

In this article, we design a reconfigurable bandwidth based on a concentric ring slot antenna using graphene. The developed antenna has good agreement between simulated and experimental results. The use of graphene in Terahertz (THz) has shown better performance than metal, and the variation in the chemical potential of graphene provides excellent performance properties, good return loss reaching −33.288 dB, bandwidth reconfiguration from 255 GHz to 406 GHz, and a good gain. These results are promising for THz applications and particularly for the application of medical imaging. The modeling and validation are performed using the CST Simulator.
