Your question is too vague for me to provide meaningful answers. Can you be more specific about the kinds of circuits and components you are interested in? Just to confirm:

\( 13.56\text{ mHz}\;=\;13.56\times10^{-3}\text{ Hz} \)

which is a very low frequency.

\( 13.56\text{ MHz}\;=\;13.56\times10^{6}\text{ Hz} \)

is in the HF region just below the 20M amateur band. I think you meant the latter rather than the former.

No schematic but have a general idea of making a wireless charger operating at 13.56mhz. I need help with the mosfet , H Bridge (Inverter) for it as well as rectifier.
You are not paying attention to anything I have said, and apparently do not understand the difference between 13.56 millihertz and 13.56 Megahertz. Please tell me how you are in any position to select components without a schematic drawing. I'd really like to know what you are thinking.

13.56Mhz(Mega Hz)

So how about a block diagram. What is the input voltage source? Why is there an inverter converting DC to AC, and why is there a rectifier? What are you trying to charge? What you are trying to do and how you are going about it is a complete mystery. Can you explain?

So the thing is I want to take a DC source and want it to be transmitted to a load (700mW to 1 watt) at 13.56mhz I.e Wireless Power Transmission

What is the voltage and power available from the source? What is the voltage level at the load? Why did you pick 13.56 MHz as a transmission frequency? In any case you need to come up with a circuit before we start choosing components.

For source we can use a 5V or 9V DC battery as it is for medical device it needs to have 13.56mhz frequency and it should have 50 to 50% efficiency
