description With the fast magnification of terahertz (THz) technology, it becomes necessary to regulate the terahertz wave transmittance resourcefully. THz filters are crucial for managing devices in THz communication. A metamaterial-based THz bandpass filter (BPF) using a complementary split-ring resonator (CSRR) is proposed with the structure of a square in pentagon (SP). The proposed filter provides high tunability over resonant frequency and bandwidth. The result shows that the resonant frequency of the designed filter is 7 THz, a maximum 3 dB bandwidth of 1.6 THz, return loss of − 28.66 dB, low insertion loss of − 0.001 dB, and the transmittance is almost 100%. The proposed THz filters are used in security screening and biomedical imaging.
