Abstract :
A particle that can be used to create an active magnetic metamaterial has been designed using an FET transistor loaded in its gate by a conducting ring and in its source by a parallel resonance circuit. The design procedure is discussed, and the working principle is experimentally demonstrated in the RF range.
