The magnitude of the electric field (dB) (a), the vector power density (b), the directivity (c) and the overall power spectrum (d) for the configuration C2 with an aperture extent of 2θ = 90° and the outer shell radius b = 49.6 mm. This case corresponds to the right-most PR resonance in Figure 6 attained for θ = 45°.
