Phương pháp hiệu quả để xác định hóa chất sử dụng sợi hình lục giác trong dải terahertz (THz)
Tóm tắt
Để phát hiện hóa chất, chúng tôi đã đề xuất một sợi tinh thể quang (PCF) với lớp vỏ lục giác và lõi hình lục giác (THz). Những lỗ khí tròn (CAHs) trong tiền đình cung cấp cơ sở cho cảm biến được đề xuất. Để phát triển và đánh giá cảm biến PCF hình lục giác, chúng tôi đã sử dụng kỹ thuật phần tử hữu hạn (FEM) và các lớp khớp hoàn hảo (PML), sử dụng các tham số quang học theo cách số. Ở đây, độ nhạy lần lượt là 92,65%, 95,25%, và 90,70%, trong khi tổn thất giới hạn thì thấp. Các giá trị 5,40 × 10−08, 6,70 × 10−08 dB/m và 5,75 × 10−08 dB/m cho ba hóa chất như Ethanol (n = 1,354), Benzene (n = 1,366) và Nước (n = 1,330) và tổn thất vật liệu hiệu quả (EML) là 0,00694 cm−1. Cảm biến Hx-PCF được đề xuất đã được thử nghiệm thành công ở tần số 1 THz. Chúng tôi chắc chắn rằng cấu trúc hình học tối ưu của cảm biến được đề xuất có thể được sản xuất và có thể đóng góp vào các ứng dụng thực tế trong y sinh và công nghiệp. Trong lĩnh vực terahertz, sợi PCF được đề xuất của chúng tôi cũng phù hợp với nhiều tín hiệu và ứng dụng y tế.
