A submilliwatt terahertz high-temperature superconductive photomixer array source: analysis and design

A continuous-wave terahertz photomixer array source made of a high-temperature superconductor material is proposed, and its radiation characteristic is studied. Employing photomixer/antenna elements in an array configuration increases the available terahertz power. It is shown that a submilliwatt terahertz power is achievable from a typical array structure. The beam steering capability of the proposed device is also investigated.
