BAND-GAP STRUCTURE ANALYSIS OF PHOTONIC CRYSTAL WITH MULTIPLE OPTICAL LAYERS LENGTHS FOR TERAHERTZ FREQUENCY RANGE
Read the full article
The article deals with formulas deduced for the infinite photonic crystal for exact definition of band-gap boundaries and width, center and edges of photonic crystal stopband with multiple optical layers lengths in twolayer cell in the frequency range from 0.1 to 1 THz. The formulas were tested by numerical simulation of photonic crystals using the transmission matrix method and method of finite-difference time-domain for the first, second and third multiplicity of optical layers lengths in two-layer cell of the photonic crystal. The formulas for the second multiplicity were experimentally confirmed.
