Acesso em:.https://repositorio.ufpa.br/handle/2011/3339In this work a new planar heterostructure of three layers with an enhanced magneto-optical Faraday and Kerr effects and extraordinary optical transmission in the wavelength region 925 to 1200 nm was investigated and optimized. This structure consists of a periodically perforated non-magnetic metallic (Au) plate, placed on two thin dielectric layers, one composed by non-magnetic material and other composed by magnetic material (Bi-Substituted Yttrium Iron Garnet) uniformly magnetized perpendicularly to its plane. Analyzing and optimizing this structure, we obtained Faraday rotation and Kerr rotation 3 times and 9 times larger, respectively, than those in analogues devices published in the literature. In addition, this structure was optimized to obtain a 40% increase of extraordinary optical transmission, preserving the angle of Faraday rotation. The investigated heterostructure can be used in non-reciprocal optical devices.porAcesso AbertoEfeito magneto-ópticoTransmissão óptica extraordináriaParâmetros físicos e geométricosDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::TELECOMUNICACOES::TEORIA ELETROMAGNETICA, MICROONDAS, PROPAGACAO DE ONDAS, ANTENAS
