wireless energy transfer experiment circuit

Hi

I have been experimenting it for a while. So I managed to generate 5V 45kHz square waveform using 555 timer with MOSFET transistor. I connect an insulated copper wire coils on drain of mosfet (I never count the number of turns). This is regarded as primary coil.

I produced more number of turns greater with ferrite rod. This would be a secondary coils. The output of secondary coil wire is connected to a diode in attempt to obtain DC voltage. So far I managed to obtain between 0.5 to 1.0V. This is not enough as I am aiming for at least 3 to 5V.

I tried to increase the number of turns in the secondary coil but no significant improvement. Any suggestion??

Is there any calculation or formula allow me to improve my experiment?

would y please show a circuit and this can describe your question more clearly

The circuit consists of 555 timer and MOSFET which is connected to pin 3 of 555 timer. The primary coil of node A and B are connected to 12V and Drain of MOSFET respectively. The frequency is approximately 50kHz.

The seconday coils has more number of turn than primary coil. A capacitor is connected across the two wires of secondary coils. A diode is connected to Node A where I use multimeter to measure the level of DC voltage.

My problem is that I could not manage to get roughly 5V. Do I require to increase the number of turns on the secondary coils.

In fact I am trying to emulate the experiment from :

But you have a lot of details there

What' s the value for capacitor connected across the two wires?
You need to find the right value for it in order to have the circuit at the resonant frequency.
