Abstract

We present an analysis of the microwave dynamics of the Superconducting Quantum Cell (SQC) in the microwave field performed by means of 3-D numerical simulations using a two-plate model. The simulations are necessary for the realization of active electrically small antennas (ESAs) based on Superconducting Quantum Arrays composed of SQCs. It was found that the incident wave mainly affects the SQC through its magnetic component in the same way as a low-frequency magnetic field does. We suggested possible improvements of the cell design by taking into account the current and field distributions in the plate intersection, as well as the size effects.
