Localization of Stochastic Electromagnetic Sources from PCBs in the Near Field

Abstract

In this paper we propose to determine the localization of stochastic electromagnetic sources from a printed circuit board in the near field using least absolute shrinkage and selection operator (LASSO) regression and correlation matrix. The printed circuit board is replaced by an equivalent model with Hertzian dipoles. The comparison between LASSO regression results and Tikhonov regularization results for stochastic electromagnetic sources are also given.
