Area of Science:

• Engineering
• Materials Science
• Computer Science

Background:

• Conformal phased arrays offer shape-changing capabilities for diverse platforms but face challenges with dynamic deformation and material limitations.
• Existing conformal arrays struggle with beam pointing errors caused by physical deformation during operation.
• Conventional printable inks for conformal arrays are costly (silver) or unstable (copper), impacting performance.

Purpose of the Study:

• To introduce a dynamic beam-stabilized processor for real-time correction of deformation-induced beam pointing errors in conformal phased arrays.
• To develop and utilize a novel, low-cost, and stable copper-based printable ink for enhanced conformal array fabrication.
• To demonstrate a unified approach for correcting both material and physical deformations in conformal phased arrays for improved performance.

Main Methods:

• Development of a silicon-integrated dynamic beam-stabilized processor with on-chip real-time control of gain, phase, and delay for each array element.
• Utilization of a low-cost copper molecular decomposition ink with minimal variation across temperature and strain (<0.1% per °C).
• Integration of the processor with the novel ink to correct residual deformities in real-time, achieving unified material and physical deformation correction.

Main Results:

• The dynamic beam-stabilized processor effectively corrects beam pointing errors caused by dynamic deformations in conformal phased arrays.
• The novel copper ink demonstrates superior stability and low cost compared to traditional silver or copper inks, maintaining trace impedance.
• The integrated system achieves real-time, unified correction of material and physical deformations, enabling robust beamforming.

Conclusions:

• The developed silicon-integrated dynamic beam-stabilized processor offers a low-power, low-area, and scalable solution for conformal phased arrays.
• This technology significantly enhances the reliability and performance of conformal arrays for on-the-move communication and sensing applications.
• The unified approach to material and physical deformation correction paves the way for practical, on-device implementations of advanced phased array systems.
