  I am designing a 4 turn toroid shape inductor on a polyimide susbtrate in order to study the inductance vs frequency graph. The core is a cobalt based alloy and it was added. Generally the inductance should drop to zero at higher frequencies but my model dose not have that drop. I ran the simulation upto 100GHz. What the reason for it ? Currnet applied: 1A

  Hi mh.pial5,
  Why do you think inductance should drop to zero at higher frequencies? It is inversely proportional to the frequency. Do you mean absolute zero?
  What is your reference here?
