The best option of carrying out the invention

The device is glued to the body of the radiating radio equipment (not shown), such as a phone, using an adhesive layer 7.

The device operates as follows. Electromagnetic wave passing through the adhesive layer 7 and the additional dielectric layer 6 and losing them a portion of their energy falls on the first metal layer 1 and at the same time (due to the presence of the coupling element 8) leads to it and the third metal layer 3 electric charge of the same sign. The thickness of the metal layers 1-3 should not exceed the value of the penetration depth in the metal of the electromagnetic waves of this frequency, so that the rays pass freely through them. Further, the electromagnetic wave passing through a thin first metal layer 1 extends in the first layer of the piezoelectric layer 4, expending energy on the reorientation of the polarization vectors of the it domain. Then, after passing through a thin metal layer 2, gets to the second layer of piezoelectric material 5, the domains which are oriented induced on the metal layer 3 of the charge in the direction opposite to the direction of orientation of the domains of the first layer of piezoe the t to refocus his domain even more energy than when passing through the first layer of the piezoelectric layer 4.
