N2 - The zonal slot cut on a conducting spherical cavity is analyzed rigorously. The slot is excited asymmetrically, which excites higher order azimuthal modes. The Green function approach is used to formulate an integral equation for the magnetic current in the slot, which is solved using the moment method (MoM). New numerical integration. In this case, the solution is very easy to implement with extremely short computation time. The effects of the latitude angle on the peak resistance and percentage bandwidth are investigated. Furthermore, the cavity resonance modes and their degeneracy are examined by plotting the expansion coefficients of the magnetic current. In addition, the problem of the rectangular slot in the nonequatorial plane is also studied. Measurements were carried out and good agreement between theory and experiment is obtained.
