摘要：

In this paper we present the theoretical analysis and the measurements of a quasi-optical band-pass filter, operating at 280 GHz. The filter consists of a metal screen, perforated periodically with cross-shaped apertures. The analysis is performed by the Method of the Moments (MoM), using entire domain basis functions. The Boundary Integral-Resonant Mode Expansion (BI-RME) method is used in the calculation of the MoM matrices. The transmission and phase shifting characteristics of the band-pass filter were measured with a Terahertz Time-Domain Spectrometer and are compared with the theoretical results. The effects of the smoothness in the cross boundary, due to the fabrication process, are also discussed.
