abstract = "This study systematically explores the integration of high-entropy alloys (HEAs) into terahertz (THz) spectroscopy and metamaterial device engineering. The research is structured into two comprehensive phases. Initially, the finite element method (FEM) was utilized to simulate the reflective behavior of a narrowband THz modulator, validating the manufacturing process's feasibility. Subsequently, a physical device exhibiting strong agreement with simulation predictions was successfully fabricated. In the second phase, the terahertz optical properties of HEA thin films were precisely characterized using terahertz time-domain spectroscopy (THz-TDS). Leveraging these properties, a transmissive metamaterial modulator was innovatively designed. The experimental results reveal that the resonance phenomena exhibited by HEA thin films can effectively substitute conventional noble metals, offering substantial cost reductions and advancing the development of high-performance THz optical components.",
