Terahertz filter based on frequency selective surfaces

摘要：

　　Terahertz filters based on the frequency selective surfaces (FSS) structure have been modeled and fabricated on the sapphire substrate.The terahertz (THz) transmission properties are investigated using a THz time-domain spectroscopy (THz-TDS) system.The designed two FSS-based THz filters exhibit the THz electromagnetic wave transmission and reflection characteristics,respectively,showing about 70% change of THz transmission at the frequency of 1.3 THz.It is suggested that the THz filtering effect results from the resonance behavior between THz plane-wave and resonant elements of designed metallic FSS structures.The agreement between experiments and simulations indicate that the designed THz filter show a great potential application for high-speed THz modulator.
