Abstract An equivalent circuit model was used to analyze a symmetrical complementary metamaterial for resonant filtering characteristic at terahertz frequencies. Using terahertz time‐domain spectroscopy system, we examined the transmittance spectra for the metamaterial structure. The experimental results validate those of the theoretical predictions. The structure could lead to be a terahertz wave bandpass filter with a narrow transmission bandwidth centered at 2.01 THz and very sharp edges. © 2011 Wiley Periodicals, Inc.
