Amidst the rapid advancements in wireless communication technology, terahertz waves, characterized by their ultra-broadband, high directivity, and high resolution within the frequency range of 0.1–10 THz, have emerged as a pivotal spectrum resource for 6G communication. Nonetheless, the escalation in frequency results in heightened path loss and diminished output power of signal sources. This poses stringent requirements on beam control devices, necessitating them to exhibit high precision, low loss, and a substantial field of view.
