This approach uses data acquired before the discharge event by using a vector network analyzer. The localization is performed by using single-shot time-domain data and the time-reversal algorithm. The time-reversal backpropagation uses experimental data, eliminating the need for numerical models of the device under test. The method allows us to distinguish two traces placed 8 mm apart.entext::journal::journal article::research article
