Research concerns efforts made to obtain more definite criteria on the feasibility of a negative-effective mass amplifier and generator system. The functioning of the new device is based on the fact that the effective masses of the charge carriers in a semiconductor may become negative under the influence of some additional energy applied from outside and supplying a sufficient amount of kinetic eneryy to the carriers. It can be achieved most conveniently with the acceleration of the carriers in the electric field. Soviet interest in the development of a NEMAG system is of importance since success in these efforts would mean the design of a practical device superior to present maser systems with regard to capability of operation in a broad band of frequencies with the possibility of being tuned within this band. A NEMAG device would also possess a very low noise figure and would operate at very high frequencies, thus presenting extremely attractive possibilities for application in reliable, long-range space communications systems.
