Theoretical analysis of the optimization of power transfer from half loop source in a simple cavity

Abstract

Abstract A model that illustrate the optimal placement of coupler inside an RF cavity is proposed. The chosen geometry of the cavity are rectangular and cylindrical cavity. A small half loop of localized current source which acts as a coupler is placed on the side of the cavity. The half loop is then rotated along an axis perpendicular to the side of the cavity. An angle which gives maximum transferred power for both cavities is then sought. The result is then compared between cavities, which is then used to estimate the optimized configuration of a half loop coupler inside an RF cavity.
