The problem of efficiency enhancing of one of the most low-voltage mm and submm waves oscillation source from 1 percent to 10 percent is set forward and solved. Sufficient, by one order, lowering of operating magnetic field is also reached. An original method and an adequate new technology permits to hope for successful solution. Preliminary results are encouraging.
