摘要

The design and simulation results of a Ku-band tunable frequency selective surface with second-order response is presented. The passband of proposed device is tuned through varying the dielectric constant of liquid crystal with external bias voltage. The unit-cell structure is presented as well as the simulated S-parameters. The results show that the proposed FSS exhibits a 3-dB bandwidth within 2...
