“…A notable example is the metasurface introduced by Ren et al in 2022. [96] This metasurface utilized elliptical CSRRs on a flexible parylene-C film, aiming to maintain a consistent phase change and uniform transmission amplitude. It demonstrated the ability to generate transmitted waves with deflection angles ranging from 38°to 13.5°w hen exposed to THz radiation within the operating range of [66] Reprinted with permission from Ref.…”

Metasurfaces have garnered significant interest owing to their inherent advantages over traditional optical components in manipulating electromagnetic waves unconventionally. Among the fundamental building blocks of metasurfaces, C‐shaped‐split‐ring resonators (CSRRs) have emerged as a highly promising option, enabling strong resonances and precise control over various characteristics of electromagnetic waves, such as phase, amplitude, and polarization. This review aims to showcase recent advancements in CSRR metasurfaces for manipulating THz waves, particularly focusing on both passive and active methods employed for controlling THz waves using single‐layer and multi‐layer CSRR metasurfaces. Moreover, this review will provide valuable insights into potential research directions in this rapidly evolving field.

In this study, we combined MATLAB with the rigorous electromagnetic field simulation software Computer Simulation Technology to perform a co-simulation method for inverse design of high-efficiency and broadband THz metasurface devices. In the proposed design method, genetic algorithm (GA) is embedded to realize automatic and inverse design. Aiming toward the different requirements of high-efficiency and broadband THz metasurface devices, different objective functions are set to optimize the design of different types of THz metasurface devices. Based on the rigorous electromagnetic simulation and genetic algorithm, the proposed design method can realize automatic and inverse design with high reliability, compared to the theoretical model based on catenary e-field theory. This study provides an important guiding role and an efficient method for designing and optimizing required metasurface devices with practical applied value.
