We use subwavelength spatial dispersion to produce a wide range of components with various features over a small footprint, at least one order of magnitude smaller than conventional passive waveguide devices.
We use topology, the mathematics of continuous transformations, to build new wave devices with unprecedented robustness against fabrication imperfections, impedance mismatches or phase disorder.
We research how to use light, sound, and vibrations to image or characterize objects in challenging situations, including lossy, disordered, or noisy environments.
