The design of near-field horizontal probe for wireless charging coil

As technology advanced, requirements for the quality of signal are also getting higher and higher. Wireless transmitted device is easier to organize than wire's one. But the efficiency of wireless device is less then wire device, and also cause electromagnetic interference (EMI). In recent years, wireless charger is getting more popular. It efficiency of power conversion is not very well for now. To enhance the efficiency, we need to measure its electromagnetic field through near-field system. Vertical electromagnetic field need horizontal circuit probe, which is not been invented yet. In the theme of story, we are going to create a horizontal circuit probe, measure wireless charger, and get the field distribution. Through the measurement, we hope to make the charger better.
