| Abstract: | A relation of the drift velocity vs electric field which is characterized by the negative differential mobility is used to represent the RWH mechanism. Using this relation, a modelis proposed which is composed of sir coupled mode equations. The characteristicS of selfsustained oscillating frequency is calculated with this model. Its results are consistent with experiments. |
