类H型结构的太赫兹带阻滤波器
Terahertz band-stop filter with H-type structure
摘要
Abstract
In this paper,a terahertz band-stop filter based on a symmetrical H-type structure was designed,the continuous metal arms of which can flow current.By using electromagnetic simulation software CST Mi-crowave Studio 2021,the filtering characteristics of the filter were studied,and the geometric parameters of the filter were determined by changing the arm length,period length and gap of double H.The results show that the filter can realize the tunable polarization properties.Under the y-polarization condition,the transmis-sion spectrum has no obvious resonance peak in the range of 0.2-2.3 THz,but the intensity ranges from-15 dB to-3 dB.Under the x-polarization condition,a remarkably sharp dipole resonance valley occurs at 1.34 THz in the transmission spectrum,and the bandwidth and intensity are 0.15 THz and-30 dB,respect-ively.In order to verify the simulation results,the designed metamaterial filter was fabricated using microma-chining technology,and the sample was tested by transmissed-terahertz time-domain spectroscopy(THz-TDS)system.The experiment results are in good agreement with the simulation results,which verifies the feasibility of this method.关键词
