Programmable Metastructures

Highly multistable composite surfaces

The arrangement of structural elements into more complex geometries provides a novel level of control for expanding the functionality of structures. We study how the combination of functional composite elements and tailored structural geometry yields mechanical response that is more than just the sum of the individual parts. We have realized structures with precise control of shape and stiffness over their lifetime and work to solve the challenges associated with the size and control of these structures including fabrication, modelling, and actuation. Learn more

Multi-Functional Composite Materials

On the one hand, thin composite shells offer an opportunity to embed functional elements within their layup while maintaining the lightweight, integrated characteristics of the material. On the other hand, the interaction between the composite material constituents themselves provides an intriguing opportunity to enhance functionality. We leverage these aspects for applications to deployable structures, smart material actuation, and lightweight radiating elements. Learn more

Dual matrix composite deployable antennas

Mechanically Reconfigurable Antennas

We use shape adaptation of conductive surfaces as a means of programming antenna response throughout their lifetime. This approach to performance adaptation in electromagnetic systems promises to yield more lightweight and energy efficient multi-functional structures for use as satellite payloads and in terrestrial communications. 

Shape morphing metamaterial antennas

We use stretchable metamaterial patterning of antennas to control the link between shape change and antenna performance.

Multi-stable radiation pattern reconfigurable antennas

Multi-stability in structures can be linked to low-energy electromagnetic reconfiguration.
