13. Formalismo FDTD para a modelagem de meios dispersivos apresentando anisotropia biaxial / FDTD formalism for modelling of the dispersive media introducing biaxial anisotropy
This work introduces an extended two-dimensional finite difference time domain method (2D-FDTD) for the simulation of metamaterial based structures. The dispersive nature of these media is accurately taken into account through the inclusion of the Drude material models for the permittivity and permeability tensors. All tensor elements are properly accounted

14. Aplicação da técnica LOD em métodos no domínio do tempo e freqüência para modelagem de meios convencionais e metamateriais / Application of LOD technique in time and frequency domain methods for modelling conventional and metamaterial media
This work focuses on developing efficient numerical methods, both in time and frequency domains, for modeling wave propagation in structures that present conventional media and/or metamaterial media combinations, particularly the metamaterials where both permeability and permittivity are simultaneously negative. In some cases, the simulation of such structur
