Summary:
A band diagram is the fundamental for investigation of the electromagnetic properties of periodic structures such as photonic crystals in optics or electromagnetic band gap structures in antenna engineering. In this paper, the two famous computational methods, finite difference frequency domain (FDFD) and finite difference time domain (FDTD) methods are applied for band diagram calculation of 2-D photonic crystals. Both of the methods are compared due to computational time and accuracy. Furthermore the loss effects on propagation modes of periodic structures have been investigated and the relationship between normalized frequency and changing the loss of the periodic structures has been found.
