Effet de l'hétérogénéité diélectrique sur un brin métallique à 915 MHz

Abstract : The effect of window in the external dielectric surrounding a wire is examined by means of two approach methods. The first method yields analytical results but ignores the singularities in the dielectric to achieve this result. The second method integrates the singularities of the field in the window and yields a final result by means of numerical computations. The two methods are complementary and compatible, then they give results which are near to each other for the propagation constant. The second method is adapted to the best result of a given technical situation. This study has put in light that a window in the dielectric sheath locally increases the electric near field.This result can be used in hyperthermical applications in biology and in medecine, so the way to technological transferts are opened
