We developed an extended Fano model describing the Extraordinary Electromagnetic Transmission (EET) through arrays of subwavelength apertures, based on terahertz transmission measurements of arrays of various hole size and shapes. Considering a frequency-dependent coupling between resonant and non-resonant pathways, this model gives access to a simple analytical description of EET, provides good agreement with experimental data, and offers new parameters describing the influence of the hole size and shape on the transmitted signal.
我们基于对各种孔径大小和形状的阵列进行太赫兹传输测量，开发了一种扩展的法诺模型，用于描述通过亚波长孔径阵列的超常电磁传输（EET）。考虑到共振和非共振路径之间的频率依赖性耦合，该模型提供了对EET的简单解析描述，与实验数据吻合良好，并提供了描述孔径大小和形状对传输信号影响的新参数。
