1. Guias de onda com um ambiente para testes de uma eletrodinâmica com violação das simetrias de Lorentz e CPT / Waveguides as a way of testing an electrodynamics with broken Lorentz and CPT symmetries
We study a CPT- and Lorentz-odd electrodynamics in (3+1) dimensions, obtained by adding a Chern-Simons-like term to the usual Maxwell model, as described by the radiation sector of the Standard Model Extension. Once this term is proportional to a constant background "4-vector", (kAF), wich selects a preferred direction in the spacetime (breaking its isotropy
