Abstract	Recently, there is a growing interest in non-uniform coupled SQUID devices in the science community. Similar to how antenna array technology has moved from uniform arrays to non-uniform, sparsely populated arrays, the traditional uniform SQUID arrays evolves to an unconventional structure making these mesoscopic quantum devices (for RF reception) a feasible concept. The focus of this work covers theoretical and numerical computations which exploits well-designed coupling schemes to modeling the dynamics of the device where the behavior of the non-periodic voltage response related to the external flux exhibits an anti-peak which is present only around the zero applied magnetic field. It is know that many nonlinear dynamical systems are highly sensitive to small external perturbations, especially when they are near the onset of a bifurcation. Exploring parameter variations, such as; inductive coupling between neighboring elements, unconventional grating and fabrication parameters may lead to a significant performance enhancement. There are theoretical indications that variations in coupling could provide very high dynamic range. Application of these devices with the ability to detect and amplify will result in a new generation of electrically small antennas.
