e-field vs h-field
Hello experts,
When I read the books about EMC, I often come cross two buzz words, they are "E-field emission" and "H-field emission". I am wondering what they are meant for. Why does E-field emission focus on 30MHz-40GHz, while H-field emission is only interested in 9KHz-30MHz range? How to measure them respectively?
Thanks for your explanation.
Best regards,
