Detailed Documentation

This program is implemented in MATLAB and employs the transfer matrix method to calculate the band structure of photonic crystals. Photonic crystals are periodic dielectric structures that can create photonic band gaps where light propagation is prohibited. They have extensive applications in optoelectronics, such as photonic crystal fibers and surface-emitting lasers. The code implements layered structure analysis through matrix multiplication operations, handling electromagnetic wave propagation across dielectric interfaces with appropriate boundary conditions. Key functions include material parameter initialization, transfer matrix construction for each layer, and eigenvalue solving for dispersion relations. This program facilitates band structure analysis of photonic crystals and supports further investigation of their optoelectronic properties. Researchers are welcome to utilize this code for their scientific studies.
