Acesso em:.https://repositorio.ufpa.br/handle/2011/5605This work provides a method for the prediction of electric field intensity to Digital TV using the Dyadic Green's function. The Dyadic is a powerful mathematical tool which has symbolic simplicity and robustness, thus enabling some characteristics of the medium (such as permittivity, conductivity and permeability, for example) are considered in developing the electric field model, as well as take into account the anisotropy of the medium. In most related works using the dyadic Green's functions are related in the VHF band. This work will present from basic concepts of dyadic, developing it for the calculation of a model which can predict the electric field to the UHF band, in which systems are Digital TV. A theoretical explanation and mathematical development will be made such that a clear understanding and objective are achieved in the study of dyadic Green's functions, in a part of the theory of electromagnetism Tests were performed to confirm the applicability of the suggested formulation, making simulations that perform a comparison between measured data, from two TV stations located in the city of Belém, and the Okumura-Hata model modified, showing satisfactory results for both frequencies in VHF and UHF.porAcesso AbertoCampo elétricoTV digitalFunção de Green diádicaBelém - PAPará - EstadoAmazônia brasileiraElectric fieldDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::TELECOMUNICACOES::TEORIA ELETROMAGNETICA, MICROONDAS, PROPAGACAO DE ONDAS, ANTENAS
