two dipoles

I need to model a system where I have an oscillating dipole with a certain frequency and through its electric field I can excite another dipole. How can I simulate the interaction between two dipoles? Frequency Domain would only give one frequency for the dipoles and I need the other to be excited, and not start with the same frequency as the first one.

Umm, if the second (passive) dipole is excited by the first it will have voltages and currents at the frequency you use to drive the first one.

You might want to think about whether you want the undriven dipole shorted, open, or terminated.

Dear D Greve,
Thanks for the reply.
I don't quite understand your point, because I am simulating a quantum emitter as a point dipole. For example, I have air as the background medium and place two points that will be my electric dipoles. I want to put one of them oscillating and the other static. The field of the first one should be able to excite the other and put it oscillating with the same frequency, but I don't know how to do that. I thought about time domain but I am not able to define a point as a dipole.

Larissa,

Point dipoles are available in time domain, as shown in the attached image.

Regards,
Sergei
