To find where on a PCB the emissions might originate, you might use a simple magnetic-field probe (see figure) connected to a spectrum analyzer. You then sweep the probe manually or with an automated ...

To find emissions on individual pins or PCB traces, use E-field probes that make direct contact with your circuit. Figure 1. Near-field probe sets may include three sizes of H-field loop probes and ...

[Learnelectronics] purchased some near-field EMI probes for his tiny spectrum analyzer for about $5 on sale. Could they be any good at that price? Watch the video below and find out. The probes ...

When this device is illuminated with a THz wave, a THz evanescent field is generated just below the aperture. The presence of the planar probe changes ... in terms of the near-field effect and ...

The signal on the asymmetric superlens is two times stronger than for the symmetric superlens, as the near-field probe is placed by 200 nm closer to the top SrTiO 3 surface at which the polariton ...
