The analytical theory describing the resonant excitation and coupling of volume and surface fields on the surface of two-dimensional complex electrodynamic structures is presented. The theoretical analysis is valid over a broad frequency spectrum from mm-wave frequencies through THz and even optical frequencies. An experimental study of planar periodic structures has been carried out using a vector network analyser calibrated to operate in the 140–220 GHz frequency range. Experimental results compare resonant eigenmode formation in two periodic surface lattice structures designed to operate within the 140–220 GHz frequency band; one periodic surface lattice etched onto a metal-backed substrate and the other arranged to have an equivalent air separation. Dispersion diagrams derived from the analytical theory are presented. The results and theory are fundamental to some of the routes to the innovation of high-power, mm-wave and THz sources, solar cells, and novel sub-wavelength absorbers.

在毫米波和太赫兹频率下激发和耦合复杂电动力学表面上的体积和表面场

提出了描述二维复杂电动力结构表面共振和激发体积与表面场耦合的解析理论。理论分析在从毫米波频率到太赫兹甚至光频率的广泛频谱上都是有效的。使用矢量网络分析仪对平面周期结构进行了实验研究，该矢量网络分析仪经校准可在140–220 GHz频率范围内工作。实验结果比较了设计在140–220 GHz频带内工作的两个周期性表面晶格结构中的共振本征模式形成；一个周期性的表面晶格被蚀刻到金属衬底上，另一个表面具有等效的空气分离。给出了从分析理论得出的色散图。
