Dissertação (Programa de Pós-Graduação em Física/CCET) - Universidade Federal do Maranhão, São Luís, 2021.https://tedebc.ufma.br/jspui/handle/tede/tede/5147The present work addresses, in a simpli ed way, Appleton's model for magnetized plas mas in the context of the usual Maxwell theory and Maxwell-Carroll-Field-Jackiw (MCFJ) electrodynamics, endowed with a xed 4-vector of Lorentz symmetry violation. We begin by reviewing the essential aspects of electromagnetic (EM) wave propagation in plasmas, analy zing the scattering relations, refractive index, propagation modes, and the birefringence e ect. In the sequel, we revisit some basic aspects of Carroll, Field, and Jackiw's electrodynamics, such as the derivation of the modi ed Maxwell equations and extended scattering relations, which leads to birefringence in vacuum. Finally, we study Appleton's model in the context of MCFJ electrodynamics in order to verify the e ects of the CPT- odd term on the propaga ting modes. Using the same procedure, we nd the relations of scattering, refractive index, propagating modes, and the birefringence e ect. We highlight how the CFJ term alters the propagation indices and acts on the propagating modes.application/pdfAcesso Abertomodelo de Appleton;física de plasmas;relações de dispersão;violação da simetria de Lorentz;Appleton's model;plasma physics;scattering relations;Lorentz symmetry violation.FísicaDissertação
