High-Frequency Properties of Two-Dimensional Josephson-Junction Arrays
Abstract
This research is designed to evaluate the potential of two-dimensional Josephson-junction arrays as high-Q, tunable, EHF sources of electromagnetic radiation. To achieve usable amounts of power, the oscillations of many junctions must be in phase with each other. To assure coherent oscillations, we must understand how the oscillations of single Josephson junctions are affected by the electromagnetic environment of the other junctions in the array, as well as the circuitry used to couple radiation out of the array. Thus, we are studying the high- frequency dynamics (the ac currents and voltages) of Josephson oscillations in arrays, and the mechanisms for emission and absorption of high-frequency radiation in these arrays.
