Embedding Approach to Modeling Electromagnetic Fields in a Complex Two-Dimensional Environment
Table 2
Comparison of the total number of CGFFT iterations as a function of N and K for the conventional (i.e., incident field initial guess) and “marching on in angle” approaches. The relative reduction in the number of iterations, the CGFFT stop criterium (NMRS CGFFT), and the resulting NRMSE for on the grid also are indicated.
