ABSTRACT This is a theoretical study to showcase the possibility of constructing a two-dimensional photonic crystal (PC) by placing a geometric array of hot spots on a dielectric layer that modify locally the dielectric function of the layer in a periodic manner. The array considered is formed by 121 hot spots laid out in the shape of a square, such that the dielectric function, , is periodic. A Gaussian electromagnetic (EM) wave packet is emitted from the centre of the layer, propagating through the entire dielectric. A series of sensors placed at the end of the array near the detection zone, which model the measurement of the dispersed EM signal, collect the data and store it in files. The data collected shows a diffraction pattern with properties that can be studied through theoretical methods. The experiment is simulated using the Finite-Difference Time-Domain method (FDTD) to solve the Maxwell equations.

用电介质中的热点合成的二维光子晶体模拟

摘要 这是一项理论研究，展示了通过在介电层上放置几何热点阵列来构建二维光子晶体 (PC) 的可能性，这些热点以周期性方式局部改变层的介电函数。所考虑的阵列由 121 个以正方形布局的热点形成，因此介电函数 是周期性的。高斯电磁 (EM) 波包从层的中心发射，传播通过整个电介质。一系列传感器放置在靠近检测区的阵列末端，对分散的 EM 信号的测量进行建模，收集数据并将其存储在文件中。收集到的数据显示了具有可以通过理论方法研究的特性的衍射图案。
