利用FDTD计算二维光子晶体带隙的matlab源程序

详 情 说 明

Here is an elaboration of the topic at hand:

In order to calculate the band gap of a two-dimensional photonic crystal, we can use the Finite-Difference Time-Domain (FDTD) method. This method is a numerical technique that can solve Maxwell's equations to obtain the electromagnetic behavior of a system. To facilitate the calculation process, we can use Matlab, which is a high-level programming language that is widely used in the scientific community. Therefore, we can write Matlab source code to execute the FDTD method and calculate the band gap of the photonic crystal. With this program, we can better understand the behavior of light in a two-dimensional photonic crystal and gain valuable insights into the properties of this special material.
