New progress in the technology and applications of SOTEM
The artificial source electromagnetic method is an important technique for deep resource exploration.The key challenge is to improve the depth and precision of detection through innovative technology.The detection mode of electromagnetic methods is evolving from far-field to near-field,and the study of near-source electromagnetic methods has become an international research frontier in recent years.Building on the recent advancements in wide-field electromagnetic methods and multi-channel transient electromagnetic methods,the short-offset transient electromagnetic method(SOTEM)has been further developed and proposed.The distinguishing features of SOTEM are its stronger signals and wider bandwidth,which are advantageous for achieving the detection requirements of greater depth and higher precision.This special issue presents eight articles covering the methods,techniques,software,and applications of SOTEM,providing strong support for the growing need for high-resolution subsurface detection.
