Numerical Investigation of the System-Matrix Method for Higher-Order Probe Correction in Spherical Near-Field Antenna Measurements

Figure 3

The power in the modes of test probes with 𝜓 equal to 0^∘, 0.5^∘, 1^∘, and 2^∘. The power for each value of |𝜇|=𝐾 is obtained by summing the power of all modes with 𝜇=±𝐾. The plots are normalized so that the power in the 𝜇=±1 modes is 0 dB.
