Abstract
The microwave applicator for microwaves outputs from a guide ( ) comprises an envelope ( ) that forces microwaves to converge towards a focal point ( ) by means of a complementary central reflector ( ). A fraction of the waves reaches this point after reflection on two facets ( ), usually curved and concave, of the reflector ( ) and the envelope ( ), while the other fraction is reflected three times on three facets ( and ), the last two facets of which form part of the envelope and one of which is concave for focussing. These devices can be used for removing a concrete surface, because the microwaves cause vaporisation at the focal point ( ).
