| 英文摘要 | In this work, we propose a topologically lossless waveguide featuring an electromagnetic wave absorption stealth function, based on the Impedance Matching Principles (IMP) and Quantum Valley Hall Effect (QVHE). The metasurface unit adopts a regular hexagonal metallic-backed structure, with a thickness approximately 0.05 times the free-space wavelength. This unit can transition from C6 symmetry to C3 symmetry, enabling the opening and closing of the topological band gap. As a result, it facilitates robust topological bend transmission within the frequency range of 12.5 GHz to 14 GHz, without backscatter (with a bandwidth of 1.5 GHz), effectively achieving more than 90% electromagnetic wave absorption at 10.56 GHz. Additionally, the metasurface exhibits polarization insensitivity due to the symmetrical nature of its unit cell. To assess the performance of the proposed device, comprehensive full-wave simulations are conducted using CST Studio Suite 2022. The electromagnetic resonance structure is added to the design process of the traditional topological symmetric unit, which can realize the electromagnetic wave absorption while realizing the topological lossless transmission, and increase the versatility and wider applicability of the topological insulator. |
