Abstract
Articles including oscillating units and methods for producing the same are disclosed. An example article includes one or more oscillator units, where each oscillator unit comprises: a micro strip transmission line extending from a first end to a second end. A first termination impedance is coupled to the first end and a second termination impedance is coupled to the second end. A first transistor is coupled between the first end and the midpoint; and a second transistor is coupled between the midpoint and the second end. The micro strip transmission line has a midpoint between the first end and the second end; and each oscillator unit generates a standing wave having a predetermined wavelength in the micro strip transmission line.
