Abstract：

Source　localization　and　reconstructions　are　critical　in　successful　designs　and　developments　of　electronic　circuits　and　systems,　for　they　can　determine　undesired　radiating　sources　and　elements,　especially　in　RF　and　microwave　frequency　ranges.　The　electromagnetic　time-reversal　(TR)　method　is　one　of　the　techniques　for　source　reconstruction　for　its　algorithmic　simplicity　without　computations　involving　Green＇s　functions.　However,　the　conventional　TR　method　has　limited　accuracy　and　effectiveness　when　working　with　realistic　equipment　that　measures　field　signals　only　with　limited　frequency　bandwidth.　To　mitigate　the　problem,　this　paper　proposes　arbitrary-order　kurtosis　and　applies　it　in　the　TR　process.　Numerical　examples　show　that　kurtosis　can　work　with　band-limited　signals　effectively　for　accurate　and　practical　TR　source　localization　and　reconstructions.　©　2023　IEEE.
