摘要

A frequency-selective, tunable terahertz (THz) filter based on a flexible tape is designed and characterized for a low-cost and easy-access THz filter with a wide range of center wavelengths (CWL) from 150 to 600 μm (2.0 to 0.5 THz). With more than 85% bandpass transmission and 10 dB bandstop reflection at the CWLs, the proposed filter based on metallic crossed-slot hole arrays are fabricated on a...
