Despite three decades of effort, predicting accurately
extraordinary transmission through subwavelength hole arrays
has proven challenging. This lack of quantitative design and
modelling able 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 manuscript 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 numerical and experimental results with various illumination and detection setups is obtained, demonstrating
the suitability of this computationally efficient modelling tool to
predict the response of extraordinary transmission structures in
practical situations
