Hi all, I am new in Comsol and I'm trying to model a 4-coil system consisting of Source coil, Transmitter coil, Receiver coil and Load coil. Basically, there will be a voltage source supplied to the Source coil and the Transmitter coil which is placed beside it will pick up the magnetic field produced by the Source coil and thus current will be induced in the Transmitter coil. On the other hand, these Transmitter coil and Receiver coil are tuned to the same resonant frequency. So, magnetic field will be formed around the Receiver coil and thus current will be induced in Load coil where I need to measure the efficiency of the power transfer from Source coil to Load coil.
What I have done so far is, I use AC/DC module where I set multi-turn domain to all the coils and I excite the coil with circuit. There is a AC voltage source connected to the Source coil and I manage to simulate the magnetic flux density around the Source coil. But I do not see any magnetic field formed around the Receiver coil which is resonantly coupled to Transmitter coil.
Can someone give me some guidance on how to simulate this correctly? Thank you very much.
