Magneto-optic Study on a Transverse Gyrotropic Grating

다국어 초록 (Multilingual Abstract)

A two-dimensional scalar Helmholtz equation is derived for a transverse electric mode transverse
gyrotropic grating. In the frame of a rigorous coupled-wave analysis, a Bloch-type wave solution and
a Fourier expansion of the dielectric tensors are substituted into the Helmholtz equation to obtain
a system of ordinary differential equations, and an Airy-like internal-reflection series is applied for
better convergence. In the derivation, no approximation or estimate has been employed, and it is
easy to implement. Finally, the numerical method is tested with various parameters.
