Abstract: We propose a directive antenna for borehole radar using a horizontally polarized wave in a vertical borehole. This antenna is an array of several horizontal loop antennas, arranged ...
Abstract: During the last years, coreless current sensors based on circular arrays of magnetic field sensors have been investigated. These sensors were limited in bandwidth and accuracy by the ...
