要約(英語): We have carried out rock fracture experiments in order to elucidate the mechanism of microwave emission due to rock fracture. We revealed experimentally that microwave is emitted when metals contact each other. If metal to metal contacts happen in the rock fracture machine, it is concerned that the desired microwave emission by rock fracture is contaminated by the emission originated by the metal to metal contact. Therefore, we connected and shortened all parts of the machine by wires in order to keep the homogeneous distribution of potential. As a result, we demonstrated that the emission due to metal to metal contact was almost completely suppressed. Pursuing the rock fracture experiments using the shortened machine, we successfully detected the microwave at 300 MHz in all rock cases.
