摘要

用时域有限差分法对太赫兹阻带滤波器和金属板带光栅谐振器进行了分析。通过与连续波激励技术的结果比较，验证了脉冲激励技术宽带响应的准确性。结果表明，随着两金属板间空芯宽度的减小，透光率的带隙变宽。本文还分析了在TSBF中引入缺陷截面的谐振腔，并特别注意了空芯宽度。数值结果表明，该方法可以很容易地获得谐振频率的可调谐特性。

Wideband analysis of a stop band filter and a resonator at THz frequencies

A THz stop band filer (TSBF) and a resonator consisting of metal plates with gratings are analyzed using the finite-difference time-domain method. The accuracy of a wideband response obtained from the pulse excitation technique is verified through comparison with the results from the continuous wave excitation technique. It is shown that the bandgap in the transmittance becomes wide as the air core width between the two metal plates is reduced. A resonator, in which a defect section is introduced to the TSBF, is also analyzed with special attention to the air core width. Numerical results show that tunable properties of resonance frequencies can readily be obtained.
