A Multi-Component Sparse Near-Field Scanning with Peak-and-Trough Searching

In order to improve the efficiency of traditional near-field scanning measurement, a multi-component sparse near-field sampling method is introduced in this article. The proposed method features three strategies: equal-height searching, random distribution, and peak-and-trough searching. This method is capable of effectively detecting both peaks and troughs of near-field distribution patterns, ensuring sufficient accuracy to characterize multiple components of electromagnetic field. Two simulati
