摘要：

We have used a liquid-nitrogen-cooled scanning SQUID microscope to image room-temperature sources of high-frequency magnetic fields and electric fields. We detect the fields by monitoring their effect on the SQUID modulation depth; high-frequency magnetic fields affect the modulation depth differently than high-frequency electric fields. We briefly describe our system, explain the principle behind detection of magnetic and electric fields, and show images of some simple room-temperature samples in the 0.8-13 GHz frequency range.
