Electromagnetic wave propagation in a one-dimensional magnetic photonic crystal made of bigyrotropic magnetic
yttrium-iron garnet and nonmagnetic gadolinium-gallium garnet is theoretically investigated using the 4×4
transfer matrix method for longitudinal magneto-optical configuration. Band gaps in the electromagnetic spectrum
are numerically obtained and appear to depend on the helicity and direction of light propagation through
the magnetic photonic crystal.
Photonic band gaps (PBGs) in periodic magnetic films with striped domains separated by Bloch-type domain walls are investigated. Calculations for yttrium iron garnet (YIG) films are performed using the transfer matrix method. The dependence of forbidden gaps in the electromagnetic wave spectrum on the thicknesses of magnetic domains is numerically studied.
