Coherent radiation of gravitation waves by electromagnetic fields in dielectric systems

The gravitation radiation is analysed, which is generated by electromagnetic fields in waveguides and resonators filled by electric and magnetic dielectrics with a large constant of penetrability. A possibility of a coherent addition of gravitation waves from the system of emitters with the axial symmetry is shown. The calculated radiated power in the super-high frequency and optical ranges equals 1-10-2 erg.cm-2 c-1 for the specific energy density of the variable electromagnetic field 1010-1011 erg.cm-3 and total volume of radiators 108-109 cm3. Such radiator may be used in laboratory experiments to check the existence of gravitation waves in nature
