wireless power transmission simulation help.

I want to simulate wireless power transmission.But I am new.pleae someone suggest me how to approach?

I do not know specifically how to simulate wireless power transfer...

But it seems to me it might be similar to the old-fashioned crystal radio set, which can bring in broadcasts yet it does not require a battery. The receiver is 'powered' by the radio waves coming from the transmitter.

Thus if you can create a simulation of a transmitter and receiver, both with highly directional antennae, you could have something approaching wireless power transfer.
