The dynamics of a core-shell structured ionized particle between two parallelconductor plates, which is biased with a direct current (DC) voltage, have beeninvestigated. It has been found that an ionized particle oscillates rapidlybetween the DC voltage biased parallel conductors, where the frequency ofoscillation depends on the free-charge density carried by the particle, the DCbias voltage, and the gap across the two conductor plates. As the presentedsystem involves a spatially oscillating ionized particle, it represents anatural prototype for the electric dipole radiation source. Since the frequencyof oscillating ionized particle depends on the DC bias voltage across theparallel conductor plates, the presented device has a broad wavelengthadjustment range for the emitted radiation.
