a). Phase difference 30 degree(), d, g, j are results of normalized E – pattern with respect to phase difference, S₁₁ and Efficiency of this state, respectively. (b). Phase difference 45 degree(), e, h, k are results of normalized E-pattern with respect to phase difference, S₁₁ and Efficiency of this state respectively. (c). Phase difference 90 degree(), f, i, l are results of normalized E-pattern with respect to phase difference, S₁₁ and Efficiency of this state respectively.
