In this work, we experimentally investigate a four-band metamaterial absorber operating at THz frequencies. The metamaterials are fabricated using the maskless UV photolithography and e-beam evaporation techniques. The absorption spectra of the proposed absorber are measured using the micro-Fourier transformed infrared spectroscopy. It was demonstrated that multi-band absorption behavior originates from different individual metamaterial resonators. The thickness of the dielectric spacer plays a key role in optimizing the absorption performance, in line with the predicted results on single-band THz absorbers.}, number={4}, journal={Communications in Physics}, author={Tran, Van Huynh and Bui, Xuan Khuyen and Vu, Dinh Lam and Bui, Son Tung and Le, Thi Hong Hiep and Nguyen, Thanh Tung}, year={2020}, month={Oct.}, pages={311} }
