Microwave Demonstration of Purcell Effect Enhanced Radiation Efficiency
L. D. Stanfield, A. W. Powell, S. A. R. Horsley +2
We experimentally demonstrate a Purcell effect-based design technique for improved impedance matching, and thus enhanced radiation efficiency from a small microwave emitter. Using…
