| Popis: | The field patterns in a metallic cavity can be described by eigen modes. These electric field modes are obtained by solving the wave equation with perfect electric conductor (PEC) boundary conditions. In this letter, the authors introduce the relation between the electric field coefficients of a desired excitation function and the cavity modes coefficients, which means that for a given field pattern, we find the amplitude of the excitation modes that yield the best approximation of the desired excitation function in the cavity. This relation is done using the excitation matrix. By minimizing the error function, the optimal frequency of operation can be found and so the amplitudes of the excitations. The proposed analysis has been validated using high frequency structure simulator (HFSS) commercial software simulation. |
