Resulting subarrays after being organized based on the phase propagation metric. This metric orients the subarrays perpendicular to the effective propagation vector ﹩{{\boldsymbol{\rho }}}^{i}﹩ − ﹩{{\boldsymbol{\rho }}}^{s}﹩. To form the subarrays shown, the phase threshold was chosen to be high to exaggerate the illustration of the subarrays and their orientation. A small phase threshold will result in more subarrays with less elements per subarray. Conversely, a high threshold results in less subarrays with more elements per subarray.
