Interpolation and Self-Correction Methods for Large-Scale Electromagnetic Modeling

There are numerous scenarios where electromagnetic scattering problems require solving multiple right-hand side (RHS) systems. One of the most prominent applications is the computation of a target's monostatic radar cross section (MRCS). As the electrical size of the target increases, these calculations demand greater computational resources in both memory and time, particularly for wide angular sweeps. Additionally, the number of RHSs required to properly capture the MRCS variations grows rapidly with frequency, making high angular resolution essential.
