“…Formulas (11) can be used to estimate effective dielectric tensor components of lamellar grating consisting of materials with arbitrary anisotropy. Important applications are optically active materials and materials with anisotropy induced by electro-optic and magneto-optic effects [29,30].…”

Anisotropic lamellar sub-wavelength gratings (nanogratings) are described by Effective Medium Approximation (EMA). Analytical formulas for effective medium optical parameters of nanogratings from arbitrary anisotropic materials are derived using approximation of zeroorder diffraction mode. The method is based on Rigorous Coupled Wave Analysis (RCWA) combined with proper Fourier factorization method. Good agreement between EMA and the rigorous model is observed, where slight differences are explained by the influence of evanescent higher Fourier harmonics in the nanograting. 3292-3302 (1979).

“…In recent years, much attention has been paid to the study on physical characteristics of these magneto-optical rare-earth garnets under extreme conditions (in high magnetic field and at low temperatures) [1][2][3][4]. And, some novel experimental phenomena on magnetic properties of these materials under extreme conditions have been revealed, such as, magnetic anisotropy, temperature-dependence characteristic, magnetic saturation, and nonlinear field-dependence property [5,6].…”

In this article, we theoretically investigate the magnetic and magneto-optical properties of Nd3Ga5O12 in high magnetic fields (up to 35 T). Here, in view of the antiferromagnetism below the Néel temperature, a particular consideration of two magnetic sublattices A and B in Nd3Ga5O12 is presented. Taking account of the indirect exchange interaction, the complicated nonlinearity of magnetization (M) with the external magnetic field (He) is quantitatively described. In addition, we detailedly deduce the relation of Faraday rotation (θF) with the external magnetic fields. In our theoretical model, it is emphasized that θF strongly depends on the magnetization of the two different magnetic sublattices (MA and MB) and He. Referring to the values of MA and MB, the Faraday rotations are simulated at four different wavelengths in Nd3Ga5O12. Our theoretical results can excellently fit the experimental work by Guillot.
