“…As we did in our comparison with (Kou & Yu, 2022), we fed each array element by using the value attained at its location by the reference continuous distribution. This time, differently from the comparison with (Kou & Yu, 2022), no further optimization of the excitations has been performed. This procedure led to an excitation amplitude per ring equal to {−18.50, −10.72, −5.98, −2.49, −0.83, −0.04, 0.00, −0.63, −1.97, −3.96, −6.73, −10.34, −14.98, −21.12, −28.52} dB, which has been rounded by using the same significant digits as in Yu and Kou (2023) before computing the far field.…”
