Despite three decades of effort, predicting accurately extraordinary transmission through subwavelength hole arrays has proven challenging. The lack of quantitative design and modeling capability to take into account the inherent complexity of high frequency instrumentation has prevented the development of practical high-performance components based on this phenomenon. This paper resorts to the Method of Moments to provide not only such missing quantitative prediction but also a theoretical framework to understand and shed more light on the far-field and near-field physics of the extraordinary terahertz (THz) transmission through subwavelength hole arrays under different illumination and detection conditions. An excellent agreement between the numerical and experimental results with various illumination and detection setups is obtained, demonstrating the suitability of this computationally efficient modeling tool to predict the response of extraordinary transmission structures in practical situations.
