Research on the element structure and surface current distribution of metasurface based on characteristic mode analysis

Chun Ni,
Xin Xie,
Liang Zhang

Abstract: Scientific research has shown that the geometric structure of the metasurface has a significant impact on its ability to control the propagation of electromagnetic waves. The control of surface current can be achieved by designing the shape of the metasurface unit cell. In this paper, the traditional metasurface is studied using characteristic mode analysis, and a modified metasurface is proposed, which consists of 4 × 4 hexagonal rings with an asymmetric concave interior. The modified metasurface controls the… Show more

“…[19][20][21][22][23] Characteristic mode analysis (CMA) is widely applied in the design of metasurface antennas. [24][25][26][27][28] It can effectively assist designers in analyzing the current distribution of metasurface metal units, the frequency range of modal significance (MS), and providing a theory for the design of wideband and reconfigurable antennas. The wideband low-profile horizontally polarized omnidirectional metasurface antenna proposed in Ref.…”

“…13 The method has been widely applied in the research of MTSs, which provides a sound theory for researchers. 14,15 Therefore, the inherent pattern of the designed MTS-loaded rectenna can be screened using CMA to obtain the specific desired radiation pattern after excitation. 16,17 Therefore, the CM theory is applied to explore the primitive properties of the system.…”
