To address the issue that the traditional electromagnetically induced transparency (EIT)-like structure is highly dependent on the polarization state of incident light, a polarization-independent EIT-like metasurface structure was designed using electromagnetic field simulation software and coupled mode theory, achieving stable transmission spectral responses for arbitrary polarization directions. The metasurface was composed of four metallic triangular rings and four metallic strips, arranged on a dielectric substrate with fourfold rotational symmetry. The polarization-independent EIT-like phenomenon was caused by the destructive interference of two bright resonances from the metallic triangular rings and metallic strips. Numerical simulation results show that the metasurface exhibits an EIT-like window around 10.55 GHz with a slow-wave group delay time of 0.46 ns. By adjusting the geometric parameters of the metasurface, the EIT-like frequency and corresponding slow-wave group delay can be flexibly tuned. This design lays a solid foundation for the practical applications of EIT-like phenomena in optical sensing, slow-light devices, and optical communication systems across multiple scenarios. Additionally, it can also be extended to other frequency bands, holding potential for polarization-independent filtering, sensing, and nonlinear effect applications.
