How to make radio waves to work??

 How can we control radio waves ..  and make the object move.. is it possible and why not micro - waves
 Bcz .. we can transfer energy. can covert to mechanical in microwaves we can do like that? and by passing AC microwaves to the diodes contaning Dc accepter...
        By connecting the circuit to some of the application..

 will the heat is produced....  we can control it..

My question is ?
 How can we control radio waves ..  and make the object move.. is it possible and why not micro - waves

All photons (electromagnetic waves) can make other wave-particles move.  That's how radio antennas and microwave ovens work.  High energy lasers make things move, though violently.

What are you actually suggesting? Is it anything new?
In straightforward, classical, electromagnetic theory, an em wave, arriving at an object, will produce a force - commonly referred to as 'light pressure'. It is very weak.
There is, of course, the possibility that the em waves will produce a heating effect, which can cause expansion of gases (increases in kinetic energy) which can also cause movement.

An EM wave will also exert a force on charged particles - electrons in a wire (eg antenna) for example.
