Source Excitation Method for Calculating Electromagnetic Field Properties in Photonic Crystal Waveguides

This computational program utilizes electromagnetic field source excitation techniques to analyze propagation characteristics - including propagation constants, confinement losses, and mode field distributions - in various photonic crystal waveguides such as photonic crystal fibers, metallic waveguides, and surface plasmon waveguides. The implementation typically involves solving Maxwell's equations using numerical methods like FDTD or FEM with dipole source excitation and eigenvalue solvers for mode analysis.
