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, (Formula presented.), 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.
