is it technicli or theoretikli posible to use a cind of microwaves or
waaves to cool the materials " as we use it for heeting "
Or is this technology olready used

Rudo,

Answer is YES and YES. I will elaborate, but first I have to say
there is certain amount of guessing involved in deciphering your question.
 I do recommend use of a spellchecker in the future, to avoid possible
misunderstanding.
 One can not cool chunk of material by putting it into microwave oven
 that would conflict with the second law of thermodynamics.

 But there is a process called 'laser cooling' which is being used 
 to cool individual molecules to very low temperatures. I will give
 you few link for further reading,but first:

 Laser can be considred a 'kind of microwave'. Historically,
masers (kind of microwave lasers) were invented first, 
only later people demonstrate  lasing at  higher frequency

Here, bear in mind that light nad microwaves are both examples of the
electromagnetic waves, and behaves the similar way

This site has a photo of part of the lab setup

It is, so far, used only in a reseacrh labs.

The demonstration of the 
"Bose Einstein Condensation" is one of the recent spectacular discoveries
achieved by this technique.

Well - not discovery - but rather an experimental confirmation of
discovery, which Bose (not Boise) made in about 1922.

In practise laser cooling only works on a small number of atoms, and
very slowly. So there is certainly not yet any technology which could
build a "microwave cooler" capable of chilling your drinks.
