Application of Matrix Partitioning Technique for Analyzing the Wide-Angle Electromagnetic Scattering Problems Based on Compressive Sensing

For the wide-angle electromagnetic scattering problems, a fast computational model based on the method of moments (MoM) combining with compressive sensing (CS) theory has been proposed. Compared with MoM, the computational process is divided into the measurement and the recovery parts by the model, which can effectively enhance the efficiency. To further improve the model, a novel scheme is proposed in this paper by introducing the matrix partitioning technique, by which the computational complexity of both parts can be reduced. The basic principle of the scheme is elaborated in detail, and its effectiveness is validated through numerical examples.
